The UPS HAT (D) is a powerful uninterruptible power supply designed for Raspberry Pi, offering seamless charging and power output with dynamic path management. This HAT provides stable 5V output, ensuring uninterrupted operation for your Pi projects. It supports 21700 Li-ion batteries (not included) and is built with safety and efficiency in mind.
Key Features
- Uninterruptible Power Supply: Automatically switches to battery power if the external supply is unavailable. Keeps your system running without interruptions.
- Dynamic Path Management: Charges batteries and powers the system simultaneously. Disconnects fully charged batteries to prevent overcharging and preserve battery life.
- Battery Monitoring: Monitors voltage, current, power, and capacity in real time via the I2C interface. Displays battery level and provides low-battery alerts.
- Multi-Battery Protection: Includes overcharge, over-discharge, overcurrent, and short-circuit protections for enhanced safety and reliability.
- Pogo Pin Connector: Powers Raspberry Pi without occupying GPIO pins. Compatible with Raspberry Pi 3, 3B+, and 4B.
- USB Interfaces: Features a USB Type-C port for charging and a USB Type-A port for 5V power output.
Safety Notes
- Use only high-quality batteries from trusted manufacturers. Ensure compatibility with the HAT's specifications.
- Avoid mixing old and new batteries or different brands.
- Keep batteries away from flammable materials, children, and improper storage conditions.
- Replace batteries after their cycle life or after two years of use, whichever comes first.

Jargon buster
Plain-language definitions for the technical terms used above.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- UPS
- An uninterruptible power supply is a battery-backed power system that keeps a device running when external power is unplugged or fails. For an embedded computer, it helps prevent sudden shutdowns that can corrupt files or interrupt a project.
- USB Type-C
- A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.
