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:

    Notes:

    • Does not come with Mini USB cable. Get one here.
    • For single cell batteries only.
    • Does not feature discharge protection.
    • Can theoretically support up to 8V input, but this voids warranty.
    • Charging and discharging at the same time is untested.
