Raspberry Pi Pico UPS HAT expansion board (20121)

TheRaspberry Pi Pico UPS HAT (20121 ) is an uninterruptible power supply module for the Raspberry Pi Pico microcontroller. It includes a switching Li-po battery charger 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. Moreover, the pin contact connector allows you to "stack" other modules on top:

Key features:

• Standard Raspberry Pi Pico connector.
• Includes Li-po battery charger with dynamic power path management
• 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
• Built-in charging indicator, power indicator, allowing you to easily check the status and charge level of the battery
• Comes with development resources and manual (Raspberry Pi Pico C/C++ and MicroPython examples)
