DFR0494 Raspberry Pi UPS HAT

DFRobot DFR0494 Raspberry Pi UPS HAT is an uninterruptable power supply shield for Raspberry Pi. The device provides a power source to Raspberry Pi for an extended period when the system is powered off to avoid system damage and ensure safe shutdown. DFR0494 can also supply stable power for applications requiring mobility, such as Raspberry Pi cameras, tablet PC, and field data collection systems. DFR0494 also adopts a MAX17043 fuel gauge for accurate power detection. The Raspberry Pi onboard microcontroller (MCU) can obtain power capacity and battery voltage information directly via I²C communication. The device supports 2A maximum current output, which is suitable for more Raspberry Pi applications. The device requires a 3.7V lithium battery, which is not included.
