Re: Wemos C3 fw upload

Should not be a problem as that's the same pin as GPIO-0. On the ESP32-C3, this is not one of the strapping pins so this pin can have any state during boot. However it is possible the pin is pulled-up (or down) during boot and this might briefly change the charge of any capacitor you may have placed...
