UPS Module for Raspberry Pi Pico, Uninterruptible Power Supply (WS Pico UPS)
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)

Please Note:
A UPS is not designed to provide continuous power, merely a window period that allows a computer or other user to finalise the work at hand and shut down. It's ability to do this is dependent on the number of devices connected to the UPS. 
To establish what you can and cannot connect, calculate the total wattage you need to supply and ensure that the UPS you purchase meets that requirement.
