Hi,

Awesome artworks mate !

Yes some GPIOs are being used.

The device tree is a good place to start to look : https://github.com/raspberrypi/linux/blob/rpi-4.19.y/arch/arm/boot/dts/overlays/audioinjector-addons-overlay.dts

For codec controls :
pins : 13, 15, 16, 18, 29
GPIOs : 27, 22, 23, 24, 5

The sound card also uses the I2S gpios : 18, 19, 20, 21

I2C is shared with other applications GPIO : 2, 3

Then the other shared pins are the GND and power pins.

HI Matt / Everyone, 

Haven't received the Octo yet but I'm trying to gain some time to fix another part of my prototype which concerns Pots and Buttons. From the pictures the Octo seems to plug on top of all the pins of the Raspberry Pi but also makes them available on top. I assume some are being used by the Octo, so I would like to know which pins are then available to attach pots and buttons?

Thanks
