Features
The Pico-UPS-B is a dedicated UPS (Uninterruptible Power Supply) module designed for Raspberry Pi Pico. It incorporates Li-po battery switching charger with power path management, and voltage/current monitoring chip, allows monitoring the battery operating status via I2C bus. What is more, the male pin header make it possible to "stack" other modules on top.
1. Standard Raspberry Pi Pico header, supports Raspberry Pi Pico series boards
2. Incorporates Li-po battery switching charger with dynamic power path management, more stable power supply
3. I2C bus communication, monitoring the battery voltage, current, power, and remaining capacity in real time
4. Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, more safe and stable
5. Onboard recharging indicator, power indicator, easy to check the battery status
6. Come with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
