Overview
The UPS HAT (E) is a highly reliable uninterruptible power supply expansion board designed specifically for Raspberry Pi, ensuring seamless operation even during power interruptions. It supports up to 4× 21700 Li-ion batteries (not included) connected in series, providing a larger capacity for extended backup power. The HAT features a USB Type-C port with bi-directional fast charging, supporting PD3.0 protocols, and offers charging power of up to 40W.
Equipped with a high-performance voltage regulator, the UPS HAT (E) delivers a stable 5V output at up to 6A, sufficient for powering Raspberry Pi and additional peripherals. The onboard I2C interface allows real-time monitoring of the battery status and operating conditions. It has built-in protections against overcharge, over-discharge, overcurrent, and short circuits. LED indicators provide clear visual feedback for battery levels and charge status.
With dimensions of 56mm × 88mm, the HAT is compact yet powerful, making it suitable for various Raspberry Pi models, including the Raspberry Pi 5, 4B, and 3B+. It connects seamlessly via pogo pins without occupying GPIO resources. The UPS HAT (E) also supports simultaneous charging and power output, automatically switching to battery mode when external power is unavailable.
This makes it an ideal choice for IoT projects, automation systems, and portable applications requiring uninterrupted operation.
