Raspberry Pi 5 UPS Board

SKU: FIT0992

This is a UPS expansion board for Raspberry Pi 5, usable as a mobile power supply with stable 5V/5A output. Its intelligent power management monitors Pi status, auto-cutting power on shutdown to extend battery life/usage time. It detects outages/adapter failures, switching to UPS automatically. It auto-powers on when restored, supports software/I2C shutdown, and allows setting auto-shutdown voltage. It also features fast charging (max 3A).
