Just curious what people have done for their power supply for a Beagle Bone Black. I'm thinking of doing a Salas BIB v1.1 supply at 500mA with 650mA CCS. I thought it'd work because over USB you're supplying .5A. But I'm not sure that's enough after doing a little digging on the web. Thus far I've seen 1.2A is the recommended for a DC supply. Looking for some ideas...
