<![CDATA[[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
Felix

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
