Raspberry Pi Pico UPS HAT expansion board (19694)

The Raspberry Pi Pico UPS Module HAT (19694) Pico-UPS-A expansion board is a special UPS (uninterruptible power supply) module designed for the Raspberry Pi Pico. It includes a switching battery charger for lithium-ion batteries with power supply circuit management and a voltage/current monitoring chip that allows you to monitor the battery's operating status via the I2C bus.

Module features:

• Standard Raspberry Pi Pico connector, supports Raspberry Pi Pico series boards
• Includes a charger for lithium-ion batteries with dynamic power path control
• I2C bus communication, real-time monitoring of voltage, current, power and remaining battery capacity
• Multiple battery protection circuits: overcharge/discharge protection, overcurrent protection, short circuit protection and reverse protection, and equalizing charge function
• Built-in charging indicator, power indicator, and low battery warning light to verify that the battery is connected correctly
• Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)

Main characteristics:

• Voltage: 5V
• Control bus: I2C
• Supported battery type: 14500 lithium-ion battery (not included)

The module is designed for direct connection to the Raspberry Pi Pico connector:
