Is there a list of which GPIO pins are unused when you've got a PiFace Digital 2 attached to a Raspberry Pi 2. I'd like to solder on a 1-wire DS18B20 temperature sensor.
Thanks in advance,
Matt.

Thanks Clem. Chris Stanton mentioned that I should try to trace the lines on the board to the pins.. and doing that shows that the board only uses 3 pins (excl. 5v).. it should mean I can take my pick of the GPIO headers for my central heating home automation project 
On further inspection.. SCLK is also wired up.
