Motor Shield V2

by Kpurzycki on Tue Feb 18, 2014 4:36 pm

FAQ for the motor shield V2 states that the only Arduino UNO pins used by the shield are A4, A5, #9, #10 . Does this mean that Digital pins #0 thru #8 and #11 thru #13 and Analog pins A0 thru A5 are all available for use? Can female headers be inserted into these positions? Are any of the holes in the developer area assigned to +5v and GND? To get + and GND can 6 pin female headers be inserted and used as a means of getting more + and gnd pins. Can pins #0 and # 1 be used as digital or as PWN?

Yes and yes.

No. Other than the 4 spare PWM breakouts, the holes in the grid are all uncommitted.
To get + and GND can 6 pin female headers be inserted and used as a means of getting more + and gnd pins.

Yes. You can solder the headers in the breakout area, then run a jumper wire from 5v and GND. Strip one end of the jumper to the length of the header and solder to each of the header pins along the bottom side of the shield.
Can pins #0 and # 1 be used as digital or as PWN?

Pins 0 and 1 are the serial Rx/Tx pins on the UNO. You can use them for regular digital I/O, but you will not be able to use the serial port and may need to disconnect any circuitry from them in order to upload sketches.
