12awg, I use that for 50-60A, that's a lot for servo power.
The holes will handle 12 awg, but 14-16awg is plenty. Remember, servo pins are only good for about 5A each.
11 pins is 10 channel + XPS/JR DMSS telemetry interface. Yes, input voltage goes directly to the servos. There is a regulator on the board, 100mA which is overkill to power the CPU, LED, and Spektrum satellite receiver support.
Programming can be done through the switch and RGB LED, or via the serial interface and a PC. Yes, the Nano will with the PPM output right now, and I am working on a firmware upgrade to give it the "Xtreme" protocol that the RFU outputs normally.
The RFU can be used with Spektrum compatible devices, such as flight stabilizers, auto-pilots, etc. that support Spektrum satellite receiver input. The RFU can also output S-BUS directly, so you can plug it into an S-BUS system and replace the Futaba receiver. There is also support for Multiplex SLRX protocol, and of course PPM output for things like flight simulators.
