Beaglebone Black + Cape Case
This is a case for a Beaglebone Black board with a cape installed. The generally useful part will be the case bottom. The case top is specific to the cape we're building, so you'll want to change that to suit your application. Our cape has a little LCD display and a round selector button on it. That is what the upper two holes are for. The bottom hole is for cabling.
The through holes in the bottom are for attaching to a machine.
