Thanks very much.
I will verify that this works for me.
If so, it will be a big help!
I tried to work out the schematics but I may have just made myself even more confused.

The information above concerning the identities of the Qwiic pins used in MicroPython has been extremely helpful. I seem to have been able to claw my way out of the hole that I was in with this help!

Thanks a lot! :D :D :D

The posts above SOLVED my problem about how to understand the pin mappings by different vendors.
You simply have to trace out the schematics. No other way.
Thanks a lot AdaFruit! What a load of bananas.

Yeah, they're more about their own CircuitPython naming schemes
