DFRobot UPS HAT is an uninterruptable power supply shield designed for the Raspberry Pi Zero series, and also compatible with Pi 2/3/A+. The UPS HAT can continue to provide power to the Raspberry Pi for a certain period of time when the system is powered off, by which to avoid system damage and assure safe shut down. In addition, the product can be used to supply power for applications requiring mobility such as Raspberry Pi camera, tablet PC, field data collection system.

DOCUMENTS
Jargon buster
Plain-language definitions for the technical terms used above.
- Fuel gauge IC
- A battery-monitoring chip that estimates how much charge is left in a rechargeable battery. It matters because it lets a microcontroller report battery level or take action before the project shuts down unexpectedly.
- 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.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- 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.
