I've a ton of questions and rather than spread them out in irrelevant threads I'll just start this thread.
Right now I'm trying to figure out the best way to power and program the P2. I'd really like to use an external supply, not my pc's usb power. I also don't want to use the USB Aux connector, this would require cutting a cable. I really WANT to power from the 2pin header that I assume is for a fan. I've looked at the schematic and I don't quite understand what would happen if I inject 5v at this point and connect either usb (or both) to a computer.
I've looked at getting a cheap 3amp usb wart like used with the raspberry pi but I'm not sure I trust the cheap supplies. I'm about ready to cut up a usb cable but I don't really want to if I don't have to!
