3. [M5Paper] - optional LED indicating ESP32 is powered or not

[M5Paper] - optional LED indicating ESP32 is powered or not


  • Hi guys

    I am experimenting with M5Paper and shutdown mode and I found it difficult to tell whether the ESP32 is powered or not. A built in LED on a GPIO would help to know the power state.

    (In comparison M5CoreInk has a builtin LED on GPIO10 which indicates the power state.)

    Thanks

  • It is quite easy to display any kind of indicator about power state on screen, small (or large) icon, text, etc...

  • Hello @loboris

    thank you for your suggestion. Unfortunately an on the screen indicator would not be updated properly if the M5Paper is turned off by pressing the reset / power off button. That is where an LED indicator, which is independent of the screen, would come in handy.

    Thanks
    Felix
