Uninterruptible Power Supply For Pico
Keeps Your Pico Running While Recharging, Monitoring Battery Status Via I2C

Features At A Glance
The Pico-UPS-A is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates Li-ion battery switching charger with power path management, and voltage/current monitoring chip, allows monitoring the battery operating status via I2C bus.
- Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series boards
- Incorporates Li-ion battery switching charger with dynamic power path management, more stable power supply
- I2C bus communication, monitoring the battery voltage, current, power, and remaining capacity in real time
- Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
- Onboard recharging indicator, power indicator, and battery warning indicator to check if the battery is connected correctly
- Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)

Jargon buster
Plain-language definitions for the technical terms used above.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- Power path
- A power path is the route electricity takes from one or more supplies to the circuit being powered. Understanding the power path helps you choose parts that can safely handle source selection, backup power, and supply switching.
- Short circuit protection
- A safety feature that helps protect the device if its output or wiring is accidentally connected in a way that causes excessive current flow. This matters in automation wiring because mistakes or damaged cables can otherwise destroy the sensor or power supply.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
