Disable Builtin LED

Unread post by dork3nergy »

Is anyone aware of how to programatically disable the built-in Tx/Rx LED on the ESP32-01 Breakout? If you are polling for a button press for example, the thing is blinking constantly. It's a real waste of power. Hopefully there is a way without having to remove the LED completely.

Cheers.

There isn't an easy way if you power the board from the USB connector. However, if you power from the Vin pin the LEDs are automatically unpowered but so is the USB to Serial converter. I assumed that powering from the USB connector means that there's ample power available.
