I have my project entering deep sleep and the only LED that’s left on is the Thing’s red power LED. Can this be turned off in software? It would be ideal if I could just have it be on if the board is awake or powered over USB, but not if the board is asleep and on battery power.
Anyone know how to do this?
Thanks.
There had been a previous discussion regarding this issue. viewtopic.php?t=48815
As far as I know, you can’t turn it off by software.
Hi @mhixson / @rpiloverbd,
The “previous discussion” was about an earlier product - the ESP32 Thing - but the information is valid for this board too. You can disable the LED by cutting the PWR jumper on the back of the circuit board.
If you haven’t worked with jumpers before, please see our tutorial here:

You will still have: the blue STAT LED available on pin 13; and the WS2812 RGB LED on pin 2. There is a test sketch (code example) showing how to use the RGB LED:

The schematic shows which pins are connected to which devices:
