From the project
A tiny Li-Po/Li-Ion charging management SoM
This is intended to be a small sized, general purpose LiPo charge controller with power path and a 3v3 regulator. Currently the targeted size is 0.7" by 0.7", or just under 18mm square. It is intended to be used with 3.7V nominal cells.
TP4056 Charge Controller 500mA charging current Low voltage trickle charging Over/Under-voltage Protection AP9101CK6 + FS8205 Disables cell on over/under charge Power Path Provides power via USB when connected 500mA max output (USB or Cell) Switchable 3v3 Regulator Default off 100mA+ output Resettable Polyfuse For high current, direct battery applications…
