Overview

Product Overview

TP4056 LiPo battery charging board is a compact single-cell lithium charger module that charges 3.7V LiPo or Li-ion batteries up to 4.2V from a convenient Micro USB input, making it a practical power-management option for portable electronics and rechargeable DIY builds. Built around the TP4056 charger IC, it supports up to 1A charging and includes current protection to add safety when integrating battery power into Arduino, ESP32, Raspberry Pi Pico, wearables, small robotics, sensor nodes, and prototyping projects. Ideal for custom USB-charged devices, backup battery packs, and embedded systems that need a simple board for charging a single-cell pack without adding a separate charger.

Questions & answers

Frequently asked questions

It can charge a single-cell 3.7V LiPo or Li-ion battery used in Arduino, ESP32, Raspberry Pi Pico, and similar portable builds. It is a charger module, not a voltage regulator, so your project still needs suitable power regulation.
ShillehTek supplies this module with pre-soldered headers, reducing setup time for breadboards or jumper-wire prototyping. You still need to wire the battery and load correctly, and use a compatible single-cell lithium battery.
It accepts power through Micro USB and charges one 3.7V LiPo or Li-ion cell to 4.2V. The module supports charging up to 1A and includes current protection; it is not for multi-cell battery packs.
Yes. It is suited for USB-rechargeable portable electronics such as sensor nodes, wearables, small robotics, and embedded prototypes. Pair it with a single-cell lithium battery and any voltage regulation required by your controller and sensors.
Check battery polarity, charge state, wiring, and whether your device requires a regulated voltage different from the battery voltage. The TP4056 charging function does not replace a project-specific regulator or power-path design.
