TP4056 Lipo Charger

This module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. With Mini-USB onboard connector, you can directly connect to the computer USB port for battery charging. If USB is not available you can use an external source voltage at IN+/IN- pads Great for DIY projects.

Besides, the charging current can be adjusted by changing the on-board “VPROG” resistors:
