Using WaveShare RP2040-Zero board to put a logic analyzer on your SAO communication.

Use with recent PulseView from sigrok, and uf2 from https://github.com/pico-coder/sigrok-pico/ . See more details about the analyzer there. It's not mine.

By default the RP2040 connects to SAO pins GND->GND,D2->SDA, D3->SCL,D5->GPIO1,D6->GPIO2

You can add jumpers to the headers off the side to connect the RP2040 analog inputs to the SAO pins also.

The RP2040 3.3v isn't connected to SAO or badge.

If you'd like you can also shuffle the SAObadge pins around with the pair of unpopulated 1x6 headers and cutting the traces on the bottom.
