What is the easiest way to access unused GPIO pins? I soldered two pin connectors on top of the amp+ just for a shutdown button - what a pain.
Ideally a stackable header ribbon cable between rpi and your amp+ board would be great. Do you know of one? One would just access the unused GPIOs thru the wires in the ribbon cable. Would like a mute button and volumio has setups for volume knobs thru GPIO pins.
If this stackable ribbon cable exists how would it effect the amp+, so long as you just access the unused pins?
