The TP4056 1A Li-Ion Battery Charging Board Micro USB with Current Protection is an all-in-one linear battery charging and protection module designed for single-cell 3.7V lithium-ion or lithium-polymer (LiPo) batteries. Built around the industry-standard TP4056 linear charger IC, this board safely manages the battery charge cycle using a Constant-Current/Constant-Voltage (CC/CV) charging algorithm.
Equipped with an onboard DW01A protection IC and dual 8205A MOSFETs, the module provides complete protection against over-charging, over-discharging, short circuits, and over-current conditions when load hardware is connected to the OUT+ and OUT- terminals. Power can be conveniently supplied via its onboard Micro-USB female port or through external solder pads (IN+ and IN-).
This protection-enabled Micro-USB version is widely used in custom power banks, wireless IoT nodes, battery shields, and portable hardware projects. It connects easily via standard through-hole soldering pads (B+/B- for battery, OUT+/OUT- for system load) and is fully compatible with Arduino, ESP32, ESP8266, Raspberry Pi, and general DIY electronics.
