Has anyone tried to use the original PiFace (designed for Pi A & B) with the Raspberry Pi 2?
I used an extender for the first 26 pins on the Pi 2 so that the PiFace would fit properly and all seemed to work fine. However, the red light on the Pi 2 blinks irregularly when the PiFace is connected. This indicates overload on the Pi 2 and/or a poor power supply. However, if I replace the Pi 2 with a Pi B there is no problem.
does anyone know if this is because the PiFace is incompatible with the Pi 2? I realise that there is a PiFace 2 available but don't really want to spend another £24 if I don't need to!
