POWER MANAGEMENT HAT FOR RASPBERRY PI, EMBEDDED ARDUINO MCU AND RTC, WAVESHARE 17210

By auto starting up on specified period, and auto shutdown at other time, the HAT can greatly save the battery life. It will monitors 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. What's 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.

Features

• Standard Raspberry Pi 40PIN GPIO extension header, supports Raspberry Pi series boards
• Onboard ATmega328P MCU, supports Arduino programming
