Power Management HAT for Raspberry Pi, Embedded Arduino MCU and RTC

DescriptionThe Power Management HAT is a smart power bank designed for Raspberry Pi. With the embedded Arduino MCU and RTC, the HAT features auto power management function which allows the Pi to work more power-efficient and more safely.If youre looking for some convenient utilities for your long-term working Raspberry Pi, such as longer battery life, or auto power on-off control, this Power Management HAT would be the ideal choice.By auto starting up on a specified period, and auto shutdown at other times, the HAT can greatly save battery life. It will monitor the operating voltage/current status of the Raspberry Pi in real-time and can be configured to shut the Pi down according to the operating status. Whats more, it comes with a handy power switch for easy on or off (safely shutdown the Pi by software), to avoid data loss caused by unplugging the power supply.FeaturesStandard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boardsOnboard ATmega328P MCU, suppor
