Pi GPIO Documentation - dunkyboy - 2023 Jan 16
I'm doing a new setup on a Pi3 using a basic 8 channel relay.
There doesn't seem to be anything in the wiki about the GPIO pins.
Can someone please please point me towards any documentation on which pins connect to a relay board?
I looked at the file gpio_pins.py, but it doesn't have enough coding comments to be easily understood.
Thanks in advance.
In answer to my own question. I have discovered the relay_board addon. https://github.com/KanyonKris/relay_board/wiki
