Description
The TP4056 Lithium Battery Charger Module uses the TP4056 IC to provide a constant-current/constant-voltage charging profile for single-cell lithium-ion batteries (3.7V). It features overcharge and over-discharge protection, LED indicators for charging status, and micro-USB input for easy powering. This module is widely used in Arduino, ESP32, and other microcontroller projects requiring rechargeable battery power. It is ideal for DIY power banks, wearable devices, IoT, and portable electronics.
