This UPS (Uninterruptable Power Supply) module can keep your Raspberry Pi Pico running when power is disconnected - whether that's to move your project between power supplies, for power cuts or just reassurance for your critical project.

The board incorporates a LiPo battery switching charger with power path management. A voltage/current monitoring chip also allows you to monitor the battery operating status via the I2C bus.

The stackable design (female header under the board and male headers on top) allows you to use this with other Raspberry Pi Pico add-ons and accessories or jumper wires, making it easier to combine components and add-ons with this board whilst keeping your project compact.

The Pico UPS module comes with its own 600mAh LiPo battery in the package.

Note: Raspberry Pi Pico not included. You'll need a Pico with male headers soldered to it. You can grab a Pico here and Pico male headers here, or buy a Pico with pre-soldered headers.
