Hello. I am trying to add a Waveshare MCP23017 IO Expansion Board to my Pi Zero 2W which is already using an Electrodragon HAT for my RBG modules. The modules work great but I need some more GPIO pins (actually 4) and not sure how to add the Waveshare Board pins to the Pi 12C Bus with the HAT already on.
I do have the 3rd 16 pin connector on the HAT free (not using it) and wondering can I connect to the 12C bus thru that. Any help would be much appreciated. Thanks
