Power Management HAT with RTC for Raspberry Pi

If you’re looking for a useful tool for long-lasting Raspberry Pi, such as longer battery life or automatic power on / off, this HAT power management is the perfect choice.

This HAT can significantly increase battery life by automatically starting the device for a certain time and automatically switching it off at another time. It can be configured to monitor the Raspberry Pi voltage / current status in real time and turn off the Pi according to the operating status. In addition, the kit includes a convenient power switch for easy on / off (soft shutdown of Pi by software), preventing data loss due to power disconnection.
