Expansion Board Base for XIAO Level Battery

[PJ_Glasso]

Hi there,

So what @cgwaltney suggests works and This Thread here is a good work.

XIAO ESP32C3 Battery Charging Listener

Hi there, If I may. You have looked at the schematic, then you will be able to see the VBUS is derived from the USB being plugged in. Also from the schematic it is connected to pin 1 on the Xiao header as 5V. [A5I11] You could put a jumper with a series Resistor of 10k to an input pin and just use INPUT,PULLDOWN for configuration. When the USB is plugged in, The input will be HIGH. Something along those lines should get it done. AFAIK, the level is only available if you use a pair of inputs…

just to add to the suggestion pile.
