Morning- I flashed via tasmotizer. Ironically right when I figured out that it’s a common WiFi chipset- I was able to find pinouts all over the place. I’m going to try and paste picture here, but if I can’t, the TX is the corner pin, and RX is the one right beside it. (Obviously you’ll want to connect those to the RX and TX of your serial programming interface). The Gnd and 3.3 are located on the other two corners as you work your way around clockwise from corner to corner. Lastly- remember to push gpio to ground when you boot, to enter programming mode. Crossing my fingers this picture works - I’m posting from my phone…
