SunFounder PiPower 3 kit is a UPS solution for the Raspberry Pi 5 SBC - CNX Software
Summary
The board delivers a stable 5V/5A output, and a 32-bit CH32V003 RISC-V microcontroller takes care of power management and battery level reporting to make sure the Raspberry Pi 5 keeps running when a power failure occurs and shutdowns gracefully when the battery level is low. When I reviewed the PiPower UPS Kit with a Raspberry Pi 4 last year, I was happy with the hardware, but disappointed with the software since users had to write their own script(s) to make use of the battery monitoring function. Usage of the pipower3 utility in Linux: The rest of the documentation – available in English, German, and Japanese – provides more detail about the hardware, assembly instructions, and so on. Raspberry Pi Pico, ESP32, and Arduino boards are supported through the USB Type-A port or 8-pin header for power and two I2C connectors for battery monitoring. SunFounder Raspberry Pi 5 UPS power supply can be pre-order for $35.99 with delivery scheduled to start on July 7.
