In the last months, I make some boards based on the BeagleBone Black board (three at this time!). In these projects, I only develop the hardware platform, the carrier board where it will be mounted. For the develop of this kind of boards, mechanical information provided by the manufacturer is very important, and enough in the most cases. In the case of the BeagleBone Black board, this info is included in the Reference Manual: BBB_SRM. But I don’t find some interesting distances that I need for my boards, so I take a board, I measure it and here are the results.
As a hadrware engineer, I always look for a complete specs of the devices with I work, to ensure that when the board is manufactured, all the components fits well. In the case of the BeagleBone board, the dimensions are well documented on pages 114 and 117 of the manual. But, if you see the board, you will notice that some components goes out of the board (Ethernet connector, External power supply connector or the micro-sd card, for example):I look in many sites to try to find these measures, but I haven’t find it. And, because I really need it, I take my caliber tool, a BeagleBone board and I start measured all the dimensions I need. First, I annotate in a paper, and after, I make the BeagleBone board as a component in Altium and then I put all the dimensions on it. I use four mechanical layers to do this, I don’t want to have all the measures in the same image, I think it could be a bit confused:
Here you can download a 4-page pdf file with all the dimensions that I measure. Also, if you’re interested in the Altium project, including the BeagleBone board component, please tell me and I’ll send you by mail.
One last thing: keep in mind that I take these distances by hand, so it’s possible that exists any inaccuracy on it, so use use it under your responsibility!!!
