I’m using a Heltec Wifi Kit 32 to power one of my projects. PCB restrictions forced me to use GPIO0 as Data/Command output pin to connect a SPI tft display. This does not work with the Wifi Kit 32 V2 any more.
I have manually set GPIO0 to LOW and measured the voltage there.
It does not go to 0V, but stays at ~1.6V, so my tft is not activated
