TP4056 1A Lipo Battery Charging Board Mini USB

The TP4056 1A Lipo Battery Charging Board is a small charger module for single-cell 3.7 V lithium-ion and lithium-polymer (LiPo) batteries, with a Mini USB input. Based on the TP4056 linear charger IC, it charges the cell with constant current and then constant voltage up to 4.2 V, at up to 1 A. It is a simple way to add USB charging to Arduino, ESP32 and other battery-powered projects.

Tip: Connect the battery to the battery pads with the correct polarity, as reversing it can destroy the board. For smaller cells, lower the charge current by changing the programming resistor (for example 2 kΩ gives about 580 mA), and add a protection circuit if your cell does not already have one.
