The original Raspberry Pi, released three years ago, looked a bit long when it was first released. For a computer priced at $35, this can be expected. In the electronic world, three years is a long time, and Pi is about to be updated. Now here, the biggest changes are faster quad-core chips, better processor architecture and 1GB RAM.
The Raspberry Pi 2 Model B has a quad-core ARM Cortex A7 running at 1GHz with 1GB RAM. The chip uses ARMv7 architecture instead of the original Raspi ARMv6. When using it, it is significantly more zipper than my months-old Raspi Model B in web browsing tasks. Very, very cool, this opens a few doors for CPU-intensive applications.
Although the CPU has been updated, there are no other changes on the Pi. The LAN9514 USB/Ethernet controller can still handle USB and Ethernet. If you are looking for Gigabit Ethernet, that will not happen. With this hardware update, we won't get eMMC flash memory, SATA ports or anything groundbreaking except for the CPU. This is almost an upgrade of CPU and RAM.
All the original ports found on the Raspberry Pi Model B+ can be found on the Raspi 2; HDMI, audio, analog video, Ethernet, USB, CSI, currently unused DSI and GPIO ports have not been changed. Similarly, we are considering using this hardware version to upgrade the CPU and RAM.
Now, RAM has moved to the rear of Raspi 2, instead of the peculiar Package On Package CPU and RAM stack on the previous Raspberry Pi.
RAM chip is
, This is an 8 gigabit DDR2 RAM with the same clock rate as the RAM in the original Raspi. Don't seek to increase memory performance or speed. Instead, I'm glad that there is now a full RAM on Raspi.
Some of you may remember the "upgrades" that early adopters of the "Raspberry Pi" missed. After the first shipment of hundreds of thousands of Raspberry Pi Model B, someone
. It is not clear whether Raspberry Pi 2 will be easily upgraded like this. There are indeed 16 gigabit RAMs, but because the CPU and RAM are not in the same package, it is not just about expanding new RAM chips.
As far as software is concerned, almost everything that ran on the original Raspberry Pi will run on the Raspberry Pi 2. The functions of RaspberryPi 2 are a superset of the original Raspberry Pi. This is a brand new processor architecture; Pi 1 uses a chip with ARMv6 architecture, while Cortex A7 uses an ARMv7 architecture. This is huge. Raspberry Pi 2 can now run modern Android systems. is having a
Pi 2 may not be able to achieve functions, and Pi 1 is hard to imagine.
There is a caveat regarding the software on the Pi. The foundation sent me a Pi 2 and an SD card with a Raspbian distribution. Until I became an idiot a few times and cut off the power to the Pi 2 without performing a proper shutdown, this has been fine. The card is damaged. I downloaded the Raspbian image from the current week ago. Pi 2 will not start the image. If you are dealing with the kernel, then there
The difference between Pi 1 and Pi 2, Pi 1 and Pi 2 will have specific disk images.
Interestingly, Raspberry Pi 1 Model B+ will boot the Raspbian image of Pi 2. This is a bit interesting because the CPU on Pi 2 is actually a superset of the CPU on Pi 1. I have talked with people who have more than a century of ARM and Linux experience, but no one knows what's going on.
For the hardware, all the information you want from the GPIO pins of the Raspberry Pi is provided on the Raspberry Pi 2. This is the usual 40-pin expansion connector that we all expect, and as far as I know, there is no change between Raspi and Raspi 2.
Regarding the form factor, almost every situation compatible with Raspberry Pi Model B+ should be compatible with the new Raspi 2 Model B+. I have tested the new Pi with the following conditions
,
with
Pibow Coupe. Only Pimoroni is not compatible with the new Raspi 2, but this is only due to a piece of acrylic interfering with the new larger CPU. A pair of dikes
Shattered acrylic shots were fired throughout the room. Use a fine saw or file. In terms of external dimensions, it should be considered the same as Model B+.
There are multiple Pis in the Raspberry Pi ecosystem, but for now, Model A+ and Raspberry Pi computing modules will retain the old BCM2835 chipset. This is not to say that they will not be upgraded in the future. The circuit board layout between Pi 1 Model B+, A+ and the computing module is very similar around the CPU and RAM. The update to the "little" Pis may just be a problem for any EDA software used by the Foundation.
Historically, the Raspberry Pi Foundation has always used Model B as its flagship product, and first saw new innovations. when. . . when
And more GPIO pins,
Upgrade model A to the new design standard. If you are waiting for an ARM Cortex A7 board with A+ or computing module specifications, you may have to wait until June or July.
Since the introduction of the Raspberry Pi a few years ago, small, inexpensive ARM Linux boards have exploded. compared to
,
, Or
In the past few years, the 700MHz ARM11 CPU found in the original Raspberry Pi seemed a bit negative. This is not the fault of the Raspberry Pi. Raspberry Pi's idea is to produce small single-board Linux computers
"Clone" boards like Banana Banana and Odroid later appeared, which could use better and cheaper silicon and were not restricted by the $35 price point. There will always be better options at higher prices.
Raspberry Pi, "clone" boards and larger, more powerful, and more expensive boards (e.g.
with
The price of the board must be considered. Currently, there are few boards that match the features and price of Raspberry Pi 2. Odroid C1 matches Raspberry Pi 2 in terms of performance and functionality. However, I do not have Odroid C1, so I am not going to compare between the two.
However, I do have a Raspberry Pi Model B+. Tomorrow, I will publish some benchmark tests between Raspberry Pi 2 and Raspberry Pi Model B+.
I just happen to have one
Sit around. When monitoring the power consumption of Raspi 2, its power consumption is slightly higher than that of Raspberry Pi 1.
When booting to the Raspbian desktop, Raspberry Pi 1 consumes about 290mA of current. Once the desktop is loaded, it drops to about 250mA. Raspberry Pi 2 consumes about 340mA of current when it starts, and drops to 270mA once the desktop is loaded. The current from Raspi 1 to Raspi 2 increases slightly.
Through some experiments, I did determine that the Raspberry Pi 2 will absorb 500mA under heavy load. This is the maximum specification of USB. If your current USB power adapter is not good, you may want to buy a better adapter for Raspi 2.
I will post tomorrow about the speed and benchmarks of Raspberry Pi 2. Before that, the time to boot to the desktop can fully characterize the speed of the Raspberry Pi 2.
Using the same SD card in both tests, Raspberry Pi 2 will boot to
. In order to perform the same test, the Raspberry Pi 1 Model B+ from a few months ago will be guided to
. The test condition is "from where the Tux should appear on the Raspberry Pi on the console" to "when the CPU monitor in the corner of the screen hits the bottom". In any case, Raspberry Pi 2 is significantly faster.
Anyone who is about to release the Raspberry Pi 1 will remember the months of waiting for Newark, Farnell, Allied and RS components. Part of the reason is due to huge demand, but most of the responsibility for defaulting orders should be attributed to the Raspberry Pi foundation. This is understandable. At the time, they were looking for the success they had dreamed of.
This time, they are ready. [Eben] told us that there are currently 100,000 Raspberry Pi 2 ModelB in the warehouse. It will take time for the new Pis to enter Fry's and Microcenter, but we are waiting for a few weeks instead of the months of initial release.
In most cases, this is just an upgrade to the Raspberry Pi Model B's CPU and RAM. Currently, there is no release or software compilation specifically for Raspberry Pi 2, and the software will take full advantage of Raspberry Pi 2. The faster Raspi 2 multi-core CPU will take a while.
Raspi 2 is faster, and the larger CPU opens several doors for interesting applications. The poor CPU of the original Raspberry Pi limited the interesting applications of a small Linux board. Applications such as computer vision and any application where a large amount of I/O occurs at the same time are impossible. This hardware revision will resolve this issue.
Future updates of Raspberry Pi will include Model A + and computing modules. These may appear in a few months. You will not hear anything about the improved Raspberry Pi 2 or Raspberry Pi 3.
The detailed classification and benchmarks of Raspberry Pi 2 will be released tomorrow.
If you were to search for the word "disclosure," then it exists. At my request, the Raspberry Pi Foundation sent me Raspberry Pi 2 Model B and SD card.
Do we have any information about the price of this new version?
Oops, didn't see TL; DR... ashamed of me.
Mano invented new Meme, SOM, DR-TL, DR and DR. Looking forward to TL; DR reply to this post...
TL; DR- Dun Goofed!
Finally, I finally bought a Raspberry Pi yesterday. At least so stable.
I have the same regret. I feel this situation and I should wait a few more weeks to upgrade from Pi B to Pi B+.
No regrets at all! You cannot have too many pis. I have four and I desire more.
I just bought B+ a week ago. Should stick to it, it's a bit difficult
I did the same thing. Thankfully, Amazon has a great return policy...
Alas, I bought a few B+s at the Studio Bazar store I have seen on the weekend before the launch. They conveniently—it looks like—a good promotion, just before the release, for $30 instead of $35...Is the inside information abused?
Is this not true for all technologies? There will always be shiny new things around the corner.
This may be correct, but only a few weeks after buying your technology at the same price, buying old and newer technology is not a good move.
Adam Osborne nodded sadly.
Yes, this is cheap technology, not something like a retina iMac.
It runs Windows:
Hell has officially frozen.
You won the internet today!
It smells like raspberries...
Don't worry this is not consumer Windows 10. This is Windows IoT..., this is just another name for WinCE.
And we think M $ can be changed, and finally get one (1) Windows to rule all these windows...tsssk tsssk tsssk. Still a mess. Windows RT (will be buried shortly), Windows 10 x86/x64, Windows Phone (aka Other Windows on ARM), then Windows IoT (or WinCE...) Remember what they used to sell as Windows Phone 7 was After shooting down about a year and a half, because it uses WinCE? ).
This is just hot air. For the hype, people stopped using all these Linux variants (and RISC OS) on the Pi.
No, I can confirm that the Windows IoT version uses the NT kernel.
WinCE works on Raspberry Pi 1 (ceonpi.codeplex.com)
This is the first time in my life installing Windows.
did not expect...
Microsoft must be dissatisfied with them being locked in the future. It is powerful to influence the thinking of young people. In many ways, Windows 10 on RPi is a bad thing-there are more consumers than creators.
Yes, for sure... Android on the Pi is also bad?
This is a very good step that Microsoft has taken. If they do something to influence someone, then I will not profit from others because they do it...
I just hope they provide an easy-to-use GPIO interface... If you do, Windows might become a big deal on the Pi
If not all Google spyware is free, then yes.
Because millions of people who use Windows have never created anything? grow up.
Windows does not encourage people to write bare metal. I am not saying that RPi can solve the problem, but I would say that without the support of Micro$oft, it will encourage people to enter more embedded system programming.
In the early days of the computer age, programs were like mathematics and were free for everyone to use. There was no such thing as closed source code, because without access to the source code, your program would never run on any other system, so the architecture There are huge differences. Today, there is very little diversity structure left, like Darwinism through marketing. I think this is an indoctrination problem. If your life is filtered to see only one thing, then you will never see anything.
Windows does not encourage people to write bare metal. "
LINUX discourages people from writing bare-metal programs
BSD discourages people from writing bare metal programs
SOLARIS discourages people from writing bare metal programs
The reason is that we have the kernel module
I did not choose the option to reply to your "F", so I am replying to myself, which is a bit strange, but I guess you will not choose to reply to me either. Decades ago, I had written a bare-metal program. If Window (or iCrap) were the only OS I encountered in my life, I thought it would be impossible. It is not Linux vs Window vs BSD vs blah blah. It has nothing to do with bare metal. It allows young people to have unlimited access to new things. And I see windows as intuition.
"In the early days of the computer age, programs were like mathematics and were free for everyone to use, so there was nothing like closed source, because if your program would never run on any other system without access to the source code, Then the architecture is different. Many."
Yes, indeed, guys, this guy is purely Quentin Tardintino’s fantasy land
"This is the kid, this is the Raspberry Pi. I have installed all the latest development tools."
"Thank you, sir, but all I need is a web browser to complete my school assignments."
"Of course, but after doing this, you can start Emacs and start hacking. Or maybe you prefer VIM?"
"Thank you, sir, but I have no interest in this. I might play some games."
"Yes, after you shoot down the aliens, you can write by yourself!"
"Thank you, sir, but I would rather just use the computer."
"This is unacceptable! You need to be taken seriously!"
"Thank you, sir, but after I finish my homework and play some games, can I get authorization?"
"I think I see the problem here. You just haven't realized that you can use bare metal programming, which means freedom!"
"Thank you, sir, it sounds interesting. My sister may be interested in it-she is good at programming. But I really only need a computer to find things and play games."
"Of course, if you want to live a life on your knees, please always beg for software scrap."
"I think I'm going to the library now. They have some computers there."
That's it, "Micro $ oft" is a true sign of utopian believers who don't understand and want to be realistic. This is where I stopped reading. Enjoy your fun in the real deformation field.
Also in education, it is useful to be able to deconstruct things to see how they are made. In this regard, M$ product placement is not very useful in this regard.
Tell us more about how to carefully record all functions of the linux kernel
Then explain to us the existence of many programming manuals, which explain in detail the internal working principles of Windows.
Once again, I did not choose the right to reply to your "F", so I am replying to myself, which is a bit strange, but I guess you did not choose the option to reply to me.
Deconstructing things, I never mentioned Linux or Windows. The biggest gain in my life is that when something breaks, I can peel off the lid to find out why.
This is the product placement.
Tell us more about how the availability of Windows on the platform makes it impossible to deconstruct
I began to suspect that you are a Microsoft spam bot, and the thinking time for all your negative comments is less than 2 seconds.
It is useful to be able to deconstruct things. It is also useful to be able to load tools (pictures, videos, new computer programs, new thingamabob) that allow you to build something quickly and easily. Sometimes the two are mutually exclusive. It is always a good thing to have choices. You can load Windows on the pi to perform easier operations in Windows, and you can load linux on the pi to perform operations more suitable for linux. what happened
Do you think we should give each child some original processors and components, and then say: "Sorry, if you want to edit this picture, you need to assemble these bits and pieces into a working computer"? If someone wants to learn something, they will. If they don't, they won't. I was forced to take piano lessons when I was young. I hate it, so I'm not good at it. Later in life, I decided to play music, so I taught myself and was very good at music.
Do you want to compare the percentage of debates/producers between people who grew up on the classic C64/apple2/Amiga/ST/Linux and typed on PC magazines and those who grew up on the Windows download appz? Puh-leeze.
According to Microsoft, this is not a complete Windows 10, but "Windows 10 for IoT." According to what they have said so far, this may be a streamlined version of Windows that is friendly to manufacturers and development boards. Maybe we should wait until we actually see it before we judge it?
In other words, Redmond may have built a *nix core, which contains a visual clone of the Win10 UI and some proprietary bits, with the purpose of preventing the target audience from gaining any real control. Ironically, this is the nature of these things.
In other words, Rob is just exuding random incoherent concepts
I doubt it. I hope it is based on Windows RT code.
Waiting for judgment? Are you crazy? This is Microsoft, so let's start twitching!
Sadly, you are right. Some people can't see their noses, so they look down on anything they don't yet understand. I still don't know what Windows 10 on RPi means because I haven't seen it yet. Therefore, I chose to be optimistic about this, rather than automatically assuming the worst.
Does Windows 10 require a license or can it be installed for free? It's a shame to have to pay for a license key that is more expensive than the hardware used, isn't it?
According to Microsoft and the Raspberry Pi Foundation, anyone willing to register as a developer will be completely free, which is also free.
Thanks for your clarification. May pick up some check out android/windows.
So, in other words, you can’t actually use it for anything useful, because your clients must be registered developers
You seem to be saying that the only useful thing to do is to do things for customers.
I agree that making things for sale is useful, but I believe making things for your own use, enjoyment or learning, or sharing with other developers is also useful.
I also doubt whether Windows will be well supported on non-x86 hardware, otherwise this version will actually be 6 times faster. But it does look very useful on Linux, and it only costs $35, which is amazing.
At this year's Build conference, Microsoft has provided free Windows for mobile phones, small-screen tablets and so-called "Internet of Things" devices under 8 inches.
They can extend their "free" Windows 10 license to an RPi basis, just like an OEM. Interestingly, RPi may not have the entire secure UEFI boot. :)
I did not target the development board, so the answer to me is "yes, it may be very useful". If after getting RPi 2 I find that Microsoft's IoT Windows 10 is better than GNU/Linux in a given pet project, I will use it. If not, then not. To be honest, I don't care, I will use the platform that suits me best.
I know why you are asking this question, but to be honest, only Microsoft knows the real answer, and they have not disclosed any information about commercial licensing. Of course, this does not stop trolls and omniscient people from scolding them for what they have not done yet. Once again, how do we wait and observe what they will do before automatically assuming the worst-case scenario? Recently, the company has become more open source friendly; perhaps this is their permanent direction, not just word of mouth. Maybe not, but we don’t know yet.
I want to know how much "basic information only used to improve the experience" collected by the RPI version of Windows 10 and can turn off spyware.
Therefore, do you want RPi version 10 to be equivalent to the current developer preview version? Because this is the only mandatory information collection place I have seen on Windows 10. Given that the final release (for PC and RPi) is more than 8 months old, how can we determine what will be included? The short answer: We don't have it, but the wild guesses and conclusions are the name of the game in this forum.
Speaking of spyware, have you seen any Android phones recently? Even if you turn off all the checkboxes that even imply privacy, every button, every link visited, every photo taken, every GPS waypoint will be sent back to Google’s native language. But it’s okay because it’s not M$FT, right?
They must do this; because "the superiority of American information on every platform" is the only thing that can prevent our vital fluids from being stolen by terrorists or any terrible incident that happened last week. Think about the children!
Can't I see the analog video port on the image?
It has been moved to the 3.5mm jack in RPi B+. Take part in the show.
On B+, analog video is carried out through the headphone jack (TRRS connector).
The composite connector is combined with the 3.5mm jack socket in the B+ version. It’s still there, you just need a different cable (something like this
)
Oops, this will teach me to type a reply and have a cup of tea before posting...
Just in case no one told you that it is now part of the 3.5mm jack
It's hard to complain about getting more power at the same price, but I personally think that keeping the USB/HUB/Ethernet messy is a wrong decision.
But hey, there are other boards that got it right.
Yes, because software developers are free and don’t need to spend time writing new drivers or debugging them
I am just assuming here. I guess that unlike most SoC devices in the past ten years, those Broadcom chips may not have a built-in Ethernet mac, and therefore no usb Ethernet mac/phy. They may also not have many USB host ports, so a hub is required to use them.
Someone might read the data sheet and prove me wrong, but this is what happens when you speculate.
AFAIR, that special hub + Ethernet combination series, RPi USB has some initial timing problems. [cyk] may refer to this. Using a different chip for this can save some problems. Linux probably covers most of the drivers, so there is no difference.
It is really interesting that Broadcom has MAC and PHY in its IP. They make router chips, Ethernet switches, PHYs, etc. They can implement Ethernet MAC in SoC like SoC used on other boards.
Have you been told to review negative reviews, etc., in exchange for review units that other sites seem to have?
Even if the hardware is great (Broadcom NDA is the worst! = great), I think I will choose Odroid-C1 to lay the "foundation" for its naive behavior.
Can you be more specific than "it looks"?
If "intentional" is the driving force for his actions, don't expect reason or logic
Odroid-C1 has better hardware specifications at the same price. 1.5GHz and 1GHz, Gigabit Ethernet with internal MAC instead of USB, optional faster eMMC module.
I think this is a better choice.
Not to mention that C1 has better graphics and video core.
But it's not just the hardware that matters. Raspberry Pi can start things, supports the most operating systems, has the best support, etc.
So my opinion is:
you want:
Hardware repair, learning: Raspberry Pi
Home automation: Raspberry Pi
Run Android games: Odroid
Change my computer. Odro
Build NAS: Banana Pi / Cubieboard
It was not started by raspberry, but olimex launched the arm pc;)
Wow, were you born yesterday? The British Broadcasting Corporation (BBC) introduced the ARM PC in 1985. Decades ago, Apple delivered many Newton devices with ARM chips.
What is the better choice?
Raspberry Pi is an educational tool that is designed as a cost-effective and stable platform that can be used for long-term development platforms and fewer and fewer underlying applications. It is designed to tell kids that if you want to do more processing, you can upgrade, or you can improvise to write more efficient code.
They waited a long time to perform well, then succumbed to pressure and released an upgraded version of pi. But the speed depends on the hardware and the ability that the programmer can find in it. Therefore, compared with PC games of the same hardware, console games can achieve higher performance. Advanced engineering technology is looking for techniques to maximize the performance of the target system. This is something that a generation has forgotten, and it is also something that many of us need to learn anew.
When the costs of the two platforms are the same, the arguments of "cost-effective" and "less = more" are invalid. A better architecture means you can get the same attention in optimization work. We are not children either, so don't limit yourself to the "education" part.
See that RPi is messy at the engineer level, such as the placement of connectors, power supply (linear and switching modes), mounting holes, etc. Compared with professionally designed products of companies with experience in this field. Designing a better platform can help me make money.
Oh, you mean how people like odroid falsify the availability of parts
Oh, do you believe they won't do it again?
Odroid avoided Broadcom, so they are unlikely to be bothered by Broadcom and its interesting relationship with the RPI Foundation again.
From the odroid website:
"Can I get PCB layout files and Gerber files?
no. The ODROID project is not a complete open source hardware.
We only publish schematics. "
But the odroid developers are ashamed of their design and can’t share with us
Mrs. Todd, what's wrong with you? You seem to totally disagree with...everything.
Just because ODROID does not want to release its PCB layout resources, it does not mean that any company is satisfied with its design. I think you are very lucky to ask Intel for the latest CPU design files. If a company is willing to somehow reveal its internal workings as a magical "we are not ashamed of our product" symbol, then why did Broadcom take so long to let us finally get the video core document.
In retrospect, if something happened, the trial relationship between ODROID and Broadcom gave us ODROID-W, which in turn led us to ODROID-C1 and established a cooperative relationship with Amlogic so far. Finally, even if ODROID-W is about to be discontinued due to limited operation, I am happy that at least two products exist, and hope that RPI Foundation, ODROID and various other companies will continue to produce these types of products. Development boards, because having more project options is never a bad thing.
"Providing more options for projects has never been a bad thing."
Yes, indeed, we want our scarce software developers to spend all their time porting code to another board instead of doing new and more interesting things.
You seem to have the wrong impression that the only important cost is hardware cost, and the only important value is hardware performance. This is strange because you don’t need keen observation skills to recognize this throughout history. Technological progress, despite higher prices and worse capabilities, still has some "victory".
What’s even more confusing is that those who find their favorites become unappreciated and continue to persevere, unable to fully take the next step, and consider whether there is something they lack, something they don’t understand, maybe Will uncover the paradox that conceals its existence. Sometimes they may feel a little harsh, but then they or a friend quickly labeled it as "marketing" and scrambled to burn it lest it poisoned their mortal souls in some unknown but certainly terrifying way.
Not sure if RPi is more suitable for learning. I don't care if the platform is popular. In fact, if I force myself to write my own code from the chip documentation, I will learn more. In my book, documenting the SoC more publicly (ie no NDA) would be a better option.
If I want to use NAS, I would choose Mini-ITX with multiple SATA, more memory, CPU horsepower, and run FreeNAS and the like.
If you really want the ultimate learning experience, maybe you can get some sand from the beach, extract silicon and build a computer
Are you a paid professional troll? I did not see any positive comments from you. The most difficult part is to purify the silicon to between 99.9% and 99.9999999% required for fab work. Yes, many people want to be able to deposit, dope, mask and etch their own silicon.
"You" learn more.
What about the fourth grade children?
I kind of agree with the learning part. IMHO, it doesn't matter whether the device is "designed" for learning. It really depends on how you use the device, or determine whether you are actually "learning" or the operation on the device that can learn something.
Personally, I have been buying Raspberry pi because it is a form factor and can be easily obtained from where I live (so, I mean don’t have to worry about international shipping.) If there are other motherboards that can be easily obtained and With better performance specifications, I will buy those.
Except for the GPU.
(Show me odroid/bananaPi/orangePi that can run XBMC/Kodi and play 50fps Full HD video.)
Any other development board has the same gpu-wise nonsense as any random android device.
It is agreed that cortex-A5 is similar in structure to A7. Due to the clock speed, the 1.5GHz A5 of ODROID-C1 will show a significant performance improvement over the 900MHz A7. RAM is also faster (DDR3 on C1 vs. DDR2 on RPI2). C1 also has Gigabit Ethernet, and the Ubuntu Snappy kernel will be added to C1 soon.
All in all, unless being part of the RPi ecosystem is important to you, I think C1 will bring you more benefits.
Frankly speaking, the sudden release of RPI2 (didn't Eben say that it will be released in 2016/2017?) may be due to two reasons: the emergence of multiple RPi clones that are more affordable and more powerful; especially 35 The dollar C1, and the Ubuntu Snappy version... In the official press release, Ubuntu announced that Ubuntu Snappy OS will support C1 and Beaglebone Black without mentioning RPi (probably due to its ancient ARM v6 architecture).
I am very happy to see that both boards are released (although the release of Windows 10 RPi2 does not care...although it is a joke). But I am not only satisfied with my C1.
+1
Does c1 have audio or analog output?
I can see that this is important.
Is there any such board with VGA output?
> Does it support sound via HDMI? Yes.
>Is there an analog audio output or input? no. But you can use our USB audio adapter.
There are "HDMI to VGA" dongle from China (price of 20 dollars) or from Walmart and "USB sound card" (price of 5 dollars)
What about the GPU?
Q: Are you still using VideoCore?
Answer: Yes. VideoCore IV 3d is the only publicly documented 3d graphics core of an ARM-based SoC. We hope that over time, the Raspberry Pi will be more open, not less.
from here:
Many people did buy Raspberry Pi because of XBMC/Kodi.
No clone is executed near it.
+1 (get my odroid c1 now!)
Of course the advantage of Odroid C1 that I intend to take advantage of is the two ADC pins. I like my RPi, but it does not have an ADC and clearly becomes an educational tool. This is an oversight that I hope version 2 can overcome.
Of course, you can connect I2C and SPI-ADC and determine a good NI USB ADC, but this should be an experiment out of the box. Hook the CD and measure the light, "You know, for the kids" –
).
After switching to the Odroid world due to the huge performance shortage of the Raspberry Pi, I agree that Odroid will undoubtedly bring more benefits. The pi was great when it was first released, but early on I started to feel that the performance was very low. Even a few years ago, it was easy to provide students with an old single-core laptop for free or almost free. The ability to access eMMC storage at a speed of 100MB/s alone has a great impact on Odroid. Using Odroid, I can open a chrome tab to browse the entire website for solutions and make corrections to the program instantly. This is something that I feel very painful on pi. Even this new pi lacks the storage, Ethernet, and usb throughput that most students need to eliminate unnecessary troubles, and it requires a second regular PC solution to the encoding problem.
Lack of CEC support provided by files.
By the way, I don't have any, but when I switch, CEC will be a big ++++ for me for media devices.
What childish? The cost of manufacturing and selling equipment is high, so children have the opportunity to learn how computers and electronic products work, and at the same time greatly support the entire developer community. They took over Pi and did things that the foundation did not expect?
The only naive thing seems to be your open mind.
What is the underside of HDMI?
RAM
I think onebiozz refers to the unoccupied space directly below the HDMI port. Marked as J5. The RAM chip is far away from the HDMI port.
This is a JTAG port.
The same J5 can be used under the HDMI of Pi 1 B+, and the test point is marked as TRST_N: TDI / TDO / TWS / TCK / GND
Sounds like JTAG
JTAG
Hmm... 8-pin... maybe a lightning connector...? But it may not be. Maybe some proprietary MHL connector?
Even from the layout (no need to point out, it is JTAG), you can see that it is not a modern I/O because there are no differential tracks that take up space.
It is "dikes", not "dikes". Quite different :)
Short for diagonal milling cutter, a good choice.
Remember when the "Foundation" said that they would not release "Raspberry Pi 2" before 2017?
Correct. Eben said in the podcast
, He now changes the line to "I do not comment on unpublished products",
. It might be wise to consider everything... :)
It is wiser that they did not release Raspberry Pi Vista... What will they do when they use Raspberry Pi 8?
I can see why, if the voyeur wants to install the latest version of Android or Windows 10 on the device. Due to the old arm architecture, the CPU was an issue from the beginning (even for Linux distributions). A7 is OK (a little bit worse than Nokia 735), and we may see a 64-bit version by 2017.
The foundation also stated that they will be shipped with the box after the first production. *Shrug*, with the best will in the world, things have changed.
Still believe that prices still have a certain amount of leeway, especially now that their sales are rising.
"The foundation also stated that they will ship the boxes together after the first production run."
Tell us more about the difficulty of finding a case for the Raspberry Pi
*Shrug* Maybe it's just the R-Pi with a shell that I couldn't find at the title price.
In my opinion, the comments as early as July 2014 were considering a new development work and a complete circuit board redesign. What we get is not a redesign, but a development board (which is not a bad thing). From my point of view, it could have been called ModelC. But what prevents them from naming it RPi 2? No.
At least it is not as bad as Firefox's numbering system, which currently has reached 35.0.x, so one can say that it is nearly 3.5 times better than IE11.
The Pibow chassis has a new layer 3 to support B+ and Pi2. If you want to use Pi 2 in a case before January 2015, please contact
So we can pull your pieces.
If you want to cut, please score the cut line first :)

I like that TLDR.

Do you want to use Odroid C1 for benchmarking? I have an extra feature that I have never used before.
Ok i'm fine
Some clarifications can be made about this. My opinion is different because you don't have to rely on or wait for Broadcom to sell you its CPU + RAM.
> There are indeed 16 gigabit RAMs, but because the CPU and RAM are not in the same package, there are more issues to consider besides putting down the new RAM chips.
As long as the memory controller supports higher density and the design is predictable, it can be routed correctly according to the JEDEC pins. All that remains is to let the boot loader (u-boot?) initialize the RAM.
There is no gigabit connection. I also look forward to SATA connectors. I don't think that I will upgrade.
Banana PI has both. I bought a BPI just for use as a NAS, but I haven't tested it yet. Today, PI and its clones provide hardware support in the mainline kernel, which is good, so there is no need to extract code from untrusted sources. Of course, you still need to believe that the boot firmware of the device itself is reliable.
Yes, it is always disappointing when you cannot use your computer for unexpected purposes
Are you talking about cutting them?
I also wish to have a SATA port. In a way, this is a good thing because it prevented me from immediately taking out my credit card and purchasing the 4th Rpi.
If you need a cheap SATA, check out PogoPlug. eBay sells them cheaply, and you can flash Arch on them and shake them.
It is just a quad-core ARMv7 at 900 MHz, no USB3, no 1Gbit/s LAN, and no eMMC.
But it has I2S, analog audio/video and low power consumption, which my odroid C1 does not have.
On the other hand, RPI2 seems to be more open source than C1 (it is stuck on linux kernel 3.10 due to bin blip).
I don't know much about my C1, at least it runs at 4 times 1.5 GHz.
No audio input? Shame...
Is it suitable for Bitcoin mining now?
(joke).
At last! ! ! !
Have been waiting for this to be damned.
Does this new CPU still have an internal hardware random number generator?
If you need random sound, please hook it to the hackaday comment section
nice one
Linear regulator or switch?
It seems to be the same design as the last one (Diode Inc. PAM2306?). The two 4.7uH inductors completely fail.
Switching power supply
Okay, thank you for your quick response.
I just ordered some element 14 from Farnell, but it seems to be out of stock at the moment.
I will reply to this post as soon as I receive it.
You can try RS, they seem to have some stock...
It's too late, although the tip
It was delivered this morning.
Yes, indeed, we are all disappointed with the performance of the new $35 Raspberry Pi, which does not exceed the 12-core Xeon server.
Stop the madness!
I really like TL: DR
I don't understand that someone asked an extra question? Scanning the reviews, the only thing that surprised me was that someone asked about the price. The price is not in the article, only in TL; DR. If it was added later, it was the first time [Brian] ignored it.
In either case, why does [Brian] blame the HAD readers of *ENT** because they must provide the necessary details in a concise format-anyway, is this what he should do? Especially the following statement:
"Now here, the biggest changes are faster quad-core chips, better processor architecture and 1GB RAM."
If that is the biggest change, it means there are others, right? Then, at least the next few paragraphs (if not the whole article) are needed to be sure...Oh, [Brian] misled us, nothing else changed. If you want to separate your hair, the components and positions on the PCB will be slightly different, plus support for a better OS, but these little things can be easily inferred from the quoted sentences.
Hush. I have been trying to tolerate editing errors, but if [Brian] wants to publish an article with insults to hide his fault...
The performance of Odroid C1 is still higher than that of Raspberry Pi 2, and the price is $35
odroid C1 is a steam vessel from a company that has been certified to produce steam vessels
Obviously, it is an automobile, and I will tell my C1 to cease to exist immediately.
Raspberry PI 2 is getting Windows 10, which is great
Yes, we all remember how it worked when Microsoft ported Windows to new devices
Let us remember the port of MIPS
Alpha port
How are these structures doing today?
When Microsoft ported Windows to your chip, it was a sign of death
exactly! What is the result of Microsoft porting Windows NT to Intel architecture?
Wait for ti = o buy raspberry pi
I would like to know how the Pi Camera performance of this new camera is – do you have a chance to try it?
It should be the perfect shell for the new raspberry:
I would like to see a camera module that can provide 4k video @ 24fps for the new PI 2 for a price of about $50. If there is a PI-based 4k camera, that would be so cool...
IIRC, you can get 5MP JPEG frames at about 8fps from the sensor/GPU. Unless you compress it to hell, think that the bandwidth exceeds the USB bus...
Since the MIPI connector of the camera is the same, it may have similar limitations as the previous RPi.
> The two data channels on the CSI-2 bus provide a theoretical 2 Gbps bandwidth, which is approximately 5 MP resolution. So this is what I expect from the new camera. It is likely to have a maximum video recording resolution of 1920 pixels × 1080 pixels at about 30 frames per second.
I was about to exercise why it didn't work, but to my surprise, at least in theory, it might work, and there is some margin.
Full HD @ 30 fps encoding/compression is about 2.1MiB/sec, so 4K (@30fps) will be 4 times that of 8.5MiB/sec. You can install it on a 128GB SDXC microSD card at this rate for about 4 hours, or you can stream it from the RPi to a remote storage system through a 10/100 NIC. If the speed is 24fps, it should be reduced by about 25%, so play for 5 hours at 128GB microSD or 6.8MiB/sec.
I don't know if the RPi CSI bus can stream data to the ISP (Image Sensor Pipeline) in VideoCore IV for encoding at such a high rate, I did find a mention of 150-160Mpixels/second in Raspberry's Google cache. Pi Forum (
-Currently they are very frustrated, I want to know why). But 150 megapixels at 8.3 megapixels per second will be 18 fps. Therefore, it may not be possible, or this new BCM2836 chip has a CSI-2 bus, and the chip works in backward compatibility mode.
Sorry, I was wrong, the old RPI A/B/B+ already has a CSI-2/CCP-2 bus, but maybe the new BCM2836 CPU can provide the GPU with a transmission rate of more than 150-160Mpixel/sec for encoding.
The camera module is only RAW data from the sensor, so it is still limited by the speed of the CSI-2 bus as mentioned earlier. Even so, this is still the theoretical limit. The actual chip implementation will be lower than this, but we don't know if we don't sign the NDA.
Raspberry Pi 2, right? I am disappointed that they did not call it Raspberry Tau.
Regrettably, a non-profit foundation disappointed its supporters by releasing a new version, which they themselves said would not be released until some time. For those who have just purchased b+, this is disappointing. If 35 dollars is nothing to you, it is still too high for others.
You should probably warn others about the kill switch in the Raspberry Pi hardware. I can't believe they stopped your B+ from working when they released a new version. Maybe it's in the firmware, we can get the patch version without using the kill switch.
I know that many people will be eliminated and I know I will do it. I even considered choosing B+ when I heard the second B+, but it didn’t actually provide any major improvements. I realize it means a lot in the eyes of lovers, but I have dealt with the limited GPIO on the original PiB by learning the basics of i2c. This greatly reduces my dependence on pins. Also, B+ and apparently 2 still put Ethernet on the USB bus, which is a total spoiler for me.
:/Also just bought b +
Um...I want to buy this too
Windows fans are too easily injured.
At the price of $35.00, you must not complain about anything.
I thought that a lot of resources would be wasted when running a complete operating system, but the price of a quad-core ARM SBC is $35.00.
That is what I think. Forget Microsoft's criticism, people are criticizing this because, what is that? Affordable quad-core board? Is it better than B+ at the same price? Is it really usable now, instead of a long-term out-of-stock board of competitors?
I swear, some people just complain because they have nothing to do. Wouldn’t it take more effort to play with any non-RPi gadgets that they find so great?
When there are other options that can actually provide better hardware for the same $35, there is still some room for complaint: P
The official Raspbian image from the Raspberry Pi Foundation is suitable for both the original Raspberry Pi and Raspberry Pi2. It contains the kernel kernel.img (for ARMv6) and kernel7.img (for ARMv7) of two devices.
This explains why your new card can boot on the original Pi.
As for why the copy on the website cannot boot on Pi 2, I will try the official image with the latest firmware. But otherwise it should work.
There is no mystery here.
Yes! htttp: //emlid.com's major upgrade to Navio + Autopilot HAT hopes that the RT core of the new Raspberry Pi 2 will not take long.
I use Pi 1 Model B as a web server; I am also using SanDisk 32GB SDHC Extreme Pro card.
These sites mainly contain graphics (architects and photographers), and I want to use Raspberry Pi 2 to speed them up.
Can Raspberry Pi 2 boot with Pi 1’s Model B Raspbian image?
Thanks, louis
I am using the power switch
The job of safely shutting down the Pi is excellent
"You are not a child, you should learn to read"
Then you lost me. From time to time there are some suspicious choices, but do you directly insult your readers? What kind of guy is it?
I think this is interesting and a little weird. Perhaps it was because of complaints, which showed what he meant. O
TLDR is too big, I didn’t read this part until the first time, then skip to the article
Hello there
I’m no stranger to this, so please don’t mind if my question is naive to you.
I have been looking for a low-cost motherboard, hoping to port it to WEC7 (won the CE..new name). Now that I got this committee, my question is can I do it?
If yes, what should I do?
Usually, the SDK comes with a BSP for porting. You must find the part closest to your platform and adjust it. Not sure if the announced "free" win10 has an adaptable BSP.
BSP:
You can do it on Raspberry Pi 1.
Oh, and look, the rumors about the basic release of a new faster model are correct, because the source of the original chip has dried up.
Did they do any other work to resolve previous design flaws when making changes? No. Because it is not redesigned by selection, it is forced to purchase due to the increasingly difficult supply of original components
...Quote? Resources?
The BeagleBone Black is still $55 and has a single-core Cortex-A8 and only 512 MB RAM.
I just hope these guys can quickly move their next design to the production stage, because the Pi is quad-core and has 1 GB of RAM, so it will (psychologically) attract more users.
Hi, I am a newbie in your geek world. I want to immigrate there as soon as possible and hope to become a citizen of Odrpid or pi2. The main reason I did this is to decode the matrix, speak your native language, and build htpc for all relatives and friends to broadcast live TV, baby live! life! Goodbye Cable Bay!
Which ones are good for openelec live TV broadcast! Pi2 or Odriod?
Raspberry Pi 1 or 2 better (excellent GPU/video acceleration driver for XBMC/Kodi)
> There is no release compiled for rpi2 now
There are NetBSD builds of archlinuxarm and Raspberry Pi 2.
Hi, can I port RTEM on Rpi2 and develop new applications
