When I connect it, the #Pi shuts off. I also have problems with the same cable and a StemmaQT accessory if I try to run it off a #Firebeetle #ESP32. I feel like I'm #DoingItWrong.

Here’s a weird side-ish project of mine. A STM32G0 as a coprocessor for #CircuitPython over #StemmaQT. I hope to get this polished up when CP 8 is in release candidate.
