LiPo Charger Module (Basic)

Overview

This module is based around the TP4056 and made for charging lithium polymer batteries using the constant-current/constant-voltage (CC/CV) charging method.

Does not include discharge protection such as a DW01.

The PCB features a Mini USB port so you can directly connect to the computer USB port for battery charging. There are also direct IN +/- pads on the PCB to solder or wire directly to a power supply.

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