This shim goes between a SAO with flipped SAO connector and the badge to reverse the connector pinout.

It flips the SAO pins by default (1->5,2->6,3->3,4->4) but has solder jumpers on the back you can bodge the pin arrangement as needed.

It also breaks out the SAO pins to headers, so I can connect a logic analyzer like a raspberry pi pico with sigrok (see https://github.com/pico-coder/sigrok-pico/ for more details on how to do that) or so you can connect a programmer to the exposed programming pins on that DigiKey SAO. I used black magic probe on esp32 as debug tool to upload code to samd11 I think.
