LiPo SHIM for Pico Pimoroni

DESCRIPTION

This SHIM provides a convenient way of powering your Raspberry Pi Pico from a LiPo/LiIon battery. You can recharge the battery easily by providing power to the Pico’s USB port. Solder this neat little square to the pins on the back of your Pico, plug in a suitable lithium-ion/polymer battery and tada – a LiPo Pico! The inbuilt charging circuit means you can recharge the attached battery by supplying power to the Pico via USB, and it includes protection against over-discharge and overcurrent. There’s a power button to stop the SHIM from providing battery power when it’s not needed and turn your project on and off, as well as two LED indicators – a white one that shows when the shim is providing power and a red one to tell you when the battery is being charged.

It has been designed to be as slimline as possible so it can be sandwiched underneath other add-ons and it’s compatible with any of our batteries.

Please Note:

• You should only use this SHIM with LiPo or LiIon batteries, and you should make sure that any project involving LiPos is sufficiently protected from being dented, bent, punctured or crushed.
• Raspberry Pi Pico, battery and other Pico add-ons are not included!

Getting Started

You’ll need to solder the SHIM to the back of your Pico, with the power button at the same end as the USB port. The text on the SHIM and the pin labels on the back of the Pico should be facing each other.
