embedded system h/w hacking, yippie. look for any pin headers, maybe 4 or 5 together. if there aren't any headers look for a 4 or 5 solder pads in roll. if you find either one of these then you need to first find which pin/pad is GND, then with this knowledge in hand you can start checking voltages on the other pins/pads. You may also find a dual roll of pins/pads of anywhere from 10 - 16 pins, most likely this is the JTAG port. WARNING, mucking about your h/w can 'cause premature failure. I've accidently shorted PWR to GND before, fortunately the DC power fuse failed. Unfortunately the fuse was a very SMALL fuse that was oh so fun to replace.
