I do see a connector labeled GPIO next to the GPIO connection from the Raspberry Pi 3 B on the Beocreate 4 channel Amplifier V2.0 board but do not see and pinout diagrams available on the web. Can you point me in the right direction on the availability of GPIOs and the pinout?
I have to full board now working via Bluetooth and have stared working on the Fruitbox project which is going very well up to this point. Configuration wise I can play music from Fruitbox selected MP3s. Just need to figure out how to integrate external push buttons to the system via GPIO.
Also not aware at what the jumpers do. Is there documentation available?
