Open source tiny battery management module I made

[Erik_EDr_Tech]

Hello people! This is an open-source power management module I made to speed up hardware development; most of the stuff I do is battery-powered, and there was always that tedious part of the project in which a power management/battery handling system has to be thought out, connected together and redrawn for each PCB.

I made this module to be a drop-in solution to that problem, with a bunch of features like 4+16 ADC channels, current measurement, on/off behavior handling, temperature sensing, 2A charger, and a few other thingies. It's all running on ATtiny1616.

On top of it all, the demo board has a convenient switch to switch between ATtiny1616 UPDI for programming and serial for communication through the USB port, this makes it easy and fast to debug through serial (in case you're not using microchip original software to program).

Would love to hear your thoughts and suggestions.

Anyways, if you want to check out my (very) detailed documentation, you can do so here: https://github.com/EDrTech/bATtiny-Guard-PMG001
