Mini USB Battery Charger TP-4056 Module

The Mini USB Battery Charger TP-4056 is a compact lithium-ion/lithium-polymer battery charging board designed for single-cell rechargeable batteries. It uses the TP-4056 linear charging IC to safely charge Li-ion/Li-Po cells from a 5V USB power source such as a phone charger, power bank, or computer USB port. This module is widely used in DIY battery projects, portable devices, and embedded systems that require reliable charging with overcharge protection.

The board includes onboard status indicator LEDs to show charging and full charge conditions, a micro USB socket for power input, and pads for battery connection. Its simple design and ease of use make it a staple in low-power battery powered projects.
