The Waveshare Uninterruptible Power Supply UPS HAT (B) for Raspberry Pi, 5V Output, up to 5A Current, Pogo Pins Connector (US) is an advanced power management solution designed specifically for the Raspberry Pi series, including models such as Raspberry Pi 3, 3B+, and 4B. This device ensures seamless power delivery to the Raspberry Pi, either from an external power source or from backup batteries, providing a continuous power supply even in the event of external power failure.

This UPS HAT features a sophisticated circuit design that includes multiple battery protection mechanisms such as overcharge, over-discharge, overcurrent, short circuit, and reverse polarity protection. These features ensure the safe and stable operation of the connected devices. The onboard 5V regulator supports up to 5A continuous output, making it a robust power source for the Raspberry Pi and other connected boards via the 5V USB output.

The device utilizes I2C bus communication to monitor battery voltage, current, power, and remaining capacity in real-time. It also includes battery warning indicators to easily verify correct battery connection. The pogo pins connector allows for powering the Raspberry Pi without occupying any GPIO resources, ensuring efficient use of the board's capabilities.

Note: Li-ion and Li-po batteries are unstable and may cause fire or injury if not properly handled. Ensure compatibility with the expansion board and use batteries from reputable manufacturers, replacing them as needed based on cycle life or age.
