Li-po Charger Module

lipo_module

This Li-Po charger module is designed specifically for the Raspberry Pi Pico, Pico H, Pico W and Pico 2 W. To use it, simply plug the module and the Pico into a breadboard as shown below, connect a Li-Po battery to the module, and it’s ready to go.

When the Pico 2 W is connected to a computer or power socket via a USB cable, the indicator light on the Li-Po charger module will turn on, indicating that the battery is charging. Once the USB cable is disconnected, the Pico 2 W will automatically switch to battery power, allowing your project to continue running seamlessly.

Note

For some computers with poor performance, sometimes if you plug in your Pico 2 W to your computer with this charging module attached, it may cause the computer not to recognize your Pico 2 W.

The reason is that after plugging in, while charging the battery, the USB port voltage is pulled down, resulting in the Pico 2 W power supply is insufficient to be recognized by the computer.

In this case, you need to pull out the Li-Po charging module and then plug in the Pico 2 W again.
