a small update: I have ordered a power supply for the device, which will probably get here sometime next week. I am baffled as to why they didn't just put more USB ports on it like they did with the beaglebone black, but I'm sure there was probably a good reason for it maybe. What's really cool is the docs don't actually say what power supply you need, but I'm pretty sure it's the same as with beaglebone black.
