Weird, the breakout pin between IO21 and IO19 is silkscreened GND, but the label says NC, not connected. The dev board datasheet[0] says that pin is not connected, which would be a fun trap for someone who tried to use that pin as a ground, but a different schematic on the site says it's tied to module ground. They don't seem to have a PDF of the actual PCB anywhere I can find. 0: https://www.espressif.com/sites/default/files/documentation/esp32-wroom-32_datasheet_en.pdf https://www.espressif.com/sites/default/files/documentation/... 1: https://dl.espressif.com/dl/schematics/ESP32-Core-Board-V2_sch.pdf https://dl.espressif.com/dl/schematics/ESP32-Core-Board-V2_s...
