Hello @Elektron

good find, thank you for sharing.

It is interesting that in your case the 10k pull-down resistor already in place on N_VBUSEN wasn't strong enough (with GPIO0 set to float) and you had to configure GPIO0 to pull that line low actively. Makes me wonder if something has changed electrically inside (newer) M5Core2?

Happy Stacking!

nicely done

I have added one more block for enabling power from Servo2 module and the new Servo2.m5b can be found here: https://gitlab.com/ove.risberg/uiflowblockservo2

You still need the battery in M5Core2 or USB cable connected since the current firmware is turning off external power shortly after boot so your M5 will poweroff if no USB cable or the internal battery is connected... if the new "Servo2 enable external power" block is used the external power is enabled and you can disconnect the USB cable.

The internal battery should be charged by the external power after the new "Servo2 enable external power" block is used.

Thanks to @felmue for the code used in the new "Servo2 enable external power" block!
