Hi conor100
Most of the capacitive sensors, shields and keypads I’ve seen use I2C Communication, this library isn’t supported yet but I know that the I2C communication is possible in Galileo, I think they might work unless they have an AVR dependency to make sure look at the .cpp and .h files of the library that uses the shield or keypad. If I get one and works I'd let you know.
