This product is designed to solve the problem of power supply, a persistent challenge for the majority of IoT projects. The uninterruptible HAT will manage sources between batteries and adapters intelligently, ensuring that your device always stays powered without letting your Pi hang up or reset switches seamlessly. RTC featured integrated MCU allows you to schedule and to have full control over the power on/off tasks remotely, timely, and securely. Extensive input range and options – solar included – will provide flexibility to choose the best power options to fit your device needs.
《Description》
The Raspberry Pi needs to be always powered up on edge which is why the HAT will take care of your device, keeping it powered. You will have full control over its power! The true uninterruptible power supply for Raspberry Pi automatically switches between different power sources without causing a reset or failure on your board. A real-time clock(RTC) featured an onboard ARM® Cortex®-M0+ microcontroller lets you schedule power cycles and wake-up or soft shut down Raspberry Pi remotely. At power-sensitive applications, the device can be entered deep sleep modes and save battery. Dynamic power management means will share the load between the main source and the battery while protecting the circuit.

《Power Software》
One of the biggest problems of remote projects is keeping the devices all-time-powered on the edge and knowledge of the power status. While stacking the UPS HAT with a battery solves the problem as standalone. The user can manage the UPS HAT via the Sixfab Power Management Platform remotely. The detailed battery and main power source diagnostics are available to ease the maintenance. An ultra-lightweight service agent works on the Raspberry Pi and communicates with the platform if you have an Internet connection via ethernet, Wi-Fi, or Cellular.
