It sounds like a good idea! At a minimum you should add some kind of buffering to the signals as Jacek suggested. This can be opto-isolators, signal buffers, or logic-level converters. It really depends on how "industrial" you are trying to be. Is this a one-off, or are you trying to make several?
I have made a cape before, and I found that the bone fits best "upside down". If you think about it that way, the "cape" can be a much larger rectangle with all kinds of things broken out, power jacks added, XBEE footprint for RF, etc. Plus, you can probably fit something like that into a project box much easier. Look at this one: http://elinux.org/Beagleboard:BeBoPr-Plus Alternately, you could get into the "Grove" ecosystem over at Seeed Studios if you are wanting to cobble together a more modular solution rather than designing your own PCB. http://www.seeedstudio.com/depot/Grove-Cape-for-BeagleBone-Series-p-1718.html --David On Thu, Mar 17, 2016 at 7:44 PM, Jacek Radzikowski < [email protected]> wrote: > It looks like the terminal blocks should be the least of your worries > at the moment.
