V1 is complete and working. Communicates with my phone and can charge it without any issues. For V2 i just got 240W cable and some ideas to make my sniffer just a little bit more useful. Now the STM32 blackpill sits on the board with PA0 soldered to one CC line (from the protected ESP32 side) with a 1k resistor. This works, but in case when the protection circuit fails in some way that malforms the signal, I wont see it on the probe. One better way of doing this would be making this another board with two pass through ports and its own protection instead. That's what Im going to work on next.
