If the foundation say this is the best layout that they could get for the cost then I believe them. Clearly your heels are dug in, and the considerations I raise for ease of mounting, enclosures, and cabling are falling on deaf ears. Not deaf ears at all. Like Liz, I am not a layout person, I leave that to the very experienced professionals who sweated blood and lots of their personal time over the design.
Having plugs out in all direction may be a PITA to a minority, but if there is no alternative……there is no alternative. And certainly no alternative in the 3 or so weeks left to manufacture.
Once the diagrams are released, perhaps you would like to have a go at making the design work how YOU want it. Who knows — it might even be possible! And we will thank you for the design, and plaudits will rain down on you from heaven.
Or at least the Raspi office. Having plugs in all directions is a PITA for more than a minority, and quite likely there is an alternative see my reply to Anthony above.
Getting feedback from the users is a good idea before declaring a design final, no matter how great the designer, and particularly the designer should be available to listen and respond to comments. Likely there are reasons why some improvements are impractical, but we have no way of knowing.
Show that there is an alternative and I am sure we would listen. I think people are underestimating the sheer complexity of fitting everything on a board this size which is necessary because of the cost limitations. I believe it took over 6 weeks to layout this board.
It went from 4 to 6 layers and even then was difficult to get to this stage. However, I would ask how many companies actually get feedback from their users prior to finalising a design like this? I cannot think of any to be honest. All it would do would be delay the final design, designing something like this by committee would be painful to say the least, and probably for no perceivable benefit for the majority of users.
Put your money where your mouths are: if you think you can do better, do better. One thing we want to see come out of this project is a market for many computers around this price point. Open source and everything else you guys are fighting for. Dig around. How exactly does it pale against Arduino? And where can I buy an Arduino board for 20 quid? Congrats on getting close to release at your target price!
Wish you luck in the yields. I am interested in future uses as the core of lab instruments. Do you think of selling mere hundreds of Broadcomm chips or doing any special board runs a year or so from now? If so, what software did you use for schematic and layout? About the orientation of connectors complaints — I can see making a 3D printed enclosure of plastic or maybe ceramic that would get around that quite well.
If printed by a makerbot, it would be a little rough, but good for a test and then make a mold and fab some. Even some rough plastic enclosures could be fun if painted as an art class project for the school to use in other classes. A populated board will be approximately 10mm thick. Back in , I wrote my very first computer programs on an Apple ][ or sometimes written as Apple II , computer with 4k bytes of RAM, and integer basic.
That computer had two graphics formats. Therefore, based on my extensive personal experience, all of the graphics options of the r-Pi are significantly higher resolution, than high res. Oh dang. I replied to a somewhat rude, sarcastic question, but that question was deleted. So now my rude sarcastic response is left dangling without context. My bad. The dangers of tabbed browsing and distractions.
Picked up a child from school. Returned home. Liz tried to tell me the laws of physics had to be changed, now you say nothing can be done about it. It seems like it is a matter of choice rather than impossibility. In the remote solar power applications that I envision for this product, boxing it will require a bigger box with bulkhead connections to get around the angle problems of wiring, so the credit card size really has no value.
Ditto for the dedicated video display application I envision, which would allow this device to be powered by USB ports on the back of the TV set. It will have to be reboxed with bulkhead connectors to get around the right angle problems of the HDMI. That makes sense. The HDMI placement and connector choice does not, especially since third world computers for classroom applications are likely to use the composite video connection rather than HDMI. So let me ask this respectfully.
Casing is far more difficult than wiring. Defeating the purpose of this project entirely? Those are the people who would be using a composite video cable and a TV monitor. So you pretty much want the foundation to build you a specific model just for your needs? Furthermore, no one is stopping you from using some solder wick or a solder sucker and putting on whatever connectors you want. I plan on doing some solder work as soon as I get mine to suit my needs.
Mini HDMI. Not robust enough, and although cables are getting cheaper, full size HDMI is much more common. Also the sockets are more expensive. Very experienced board designers have been working on this board for some time. There are many many issues making a board of this size, which have been covered above. What I am saying is that connector placement was not at the top of the list. When you have a list of priorities, you start at the top and work down.
By the time connector placement gets considered, it might be impossible to move them without breaking some higher priority requirements. What is annoying is people coming in saying that can do a better job of placement when they have no idea how complicated a job it was even getting to this stage, or what priorities were given to the board designer.
Now you could argue that the priorities were wrong. But that only applies to whatever YOU want to use the board for, not what the foundation want to use the board for. But it would also change processor, memory, pin outs etc, so would be a completely different kettle of fish. The same design rules for the board will apply unless priorities change.
I doubt, but have no visibility, that a more expensive board will be designed to sell alongside the A and B, since they already cover the target market. As I said before nothing can be done with the current incarnation of the board. As I said above somewhere, once the schematics are done and released , people are welcome to re-layout the board as they want. If you can do better then you are more than welcome to try. I think you might be quite surprised at how difficult it will be to get connectors exactly where you want them and still maintain the price point required by the foundation.
You could do it by making the board bigger, almost certainly, and using different connectors, but those both increase cost too much. Jamesh, First of all, thanks for all your efforts and the great job that has been put into this design.
You mentioned that at some point the schematics will be available for those of us who would like to redo the board layout. It adds extra cost and admin by introducing new manufacturing and fulfilment steps. I know me and other few people like me are extreme cases, but making the advanced users happy, would be another power differentiation respect other boards. And some of us probably will develop advanced hardware or soft applications to raspberry.
I myself produce hdi boards at home, there are a lot of crazy people out there. Board layout is like magic to me! Not somethig you could solder at home, and if you want to buy the SoC itself you would need to go to Broadcom, and they only sell in large quantities. Can you post the picture on the other side to see the pop memory connections? Just curiosity. Thankyou, and keep the good work. So the has even more balls…. A couple of days ago, the gerbers and finals layouts for the PCBs was […].
Without that, it really becomes a nightmare to do anything in a box, and makes it almost DOA for OEM dedicated device projects with no way to secure it in a case. I believe that we are waiting for the layout guy to get back from a well deserved rest to do something about the lack of mounting holes.
Unless you are in a real harsh vibration environment, they should be OK for most use cases. I have motherboards in picture frames and a bad raspberry pi motherboard would make a nice addition. Is that a USB key in your pocket or a dual-core computer? Future versions of the device will have a USB 3 connector and faster processors. No case required either. Well, we are quite aware of that device, and have been for some time. We are not sure which SoC it uses though, perhaps a Samsung one.
Nvidia are also looking to get a patent on that form factor, which should cause a few ructions. In fact, I poo poo your poo poo. To quote a phrase. It all comes down to…if the cotton candy fulfils your needs at the price it is, you should use it. If the Raspi fills your needs at its price point, use that. Article says its an Exynos — we did wonder, and only 2 cores. Like I said — aimed at a different market.
And of course they are going to licence the design rather than make it themselves. Very different beast, for a very different market, Anthony. This visualization image is pretty cool, and gives a bit of an idea of the complexity of the […]. Ah yes, quash the dangerous ideas of people who want extravagant things like mounting holes and manageable cabling. Not dangerous ideas at all. We understand. All comments are taken in to account, and may or may not result in board redesigns as and when time permits.
Forgot to say to you guys: keep up the good work! Will take me back to my Vic days! Can you make a tape recorder interface?! Plus, more importantly, that way we could file off the corners to make them rounded, and make it genuinely credit-card shaped!
Board space costs money — not sure how much a couple of mm would add, but cost is paramount. At the moment we recommend sticky fixer style attachment! My 7 year old daughter and I are going to have some proper geek out fun with one of these, many thanks for giving back! Can you please confirm this bit of info : Liz is responsible for all the They Might Be Giants lyrics. Can you tell me what PCB design software was used for your circuit board layout and if the design files are available for download?
Hi, just to say that my calipers show 56mmx85mm. Did the board grow slightly since this was written? News All news. Raspberry Pi Gerbers - click to embiggen.

Many of the notable names in the Raspberry Pi community came to it with little or no maker skills and it was through experimentation, determination, repetitive failure, and lots of practice that they became the inventive lot they are today. Here we take a look at one of those people and the tools they use for making. Get inspired and you too could be in these pages one day.
Tim Richardson has been involved with the Raspberry Pi community from almost the start. He has some advice for those new to or thinking about getting one. Use a 3D printer with Raspberry Pi. Tim suggests that one of the best upgrades you can do is to add a Raspberry Pi computer running OctoPrint.
OctoPrint is used to control and monitor your printer, even remotely, and uses a Raspberry Pi Camera Module for creating a time-lapse video of your prints.. OctoPrint supports most consumer printers on the market, so it is likely to work with yours.
Installation is a breeze! Once you have set up OctoPrint for your printer, you can start moving the print head around essential for bed levelling and see the temperature of your print bed if it is heated and the extruder.
During printing you can watch the temperatures, see the G-code as it is executed, and watch the progress of the print on your phone or computer. He has a few tips which may help you design objects in this online tool from Autodesk.
On starting a new design, add the ruler to the workplane. Every selected shape will show dimensions which can be edited with exact sizes. This even works for rotation. When designing a mount or case for something, Tim first models the item itself, simplified but accurately measured.
He places solid blocks where ports or buttons need to be accessed. Laser cutters are the mainstay of almost all makerspaces. Tim has a few bits of advice if you are using one for the first time. Laser cutters can be used for plastic, wood, and other materials.
