[hpsdr] Beagleboard + Tin Can Tools Trainer board for SDR?

[Erik Anderson]

Would it be possible for a beagleboard to be hooked up to the atlas without
overloading the LPU with the other boards or causing signal interference?
 I've seen quotes somewhere that it uses 5v @ 500mA, but I'm having trouble
figuring out where I read that now...
