Raspberry Pi Power Management & UPS HAT

Rated 4.50 out of 5 based on 2 customer ratings
(2 customer reviews)

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.

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.

Power Software Features

  • Charging status, Battery Percentage, and Health
  • Main Power Source Plugged or Unplugged
  • Input/Output Voltage Level and Current Consumption
  • Temperatures of Raspberry Pi, HAT, and Battery Holder Board
  • Cooling Fan Working Status and RPM
  • Custom Time Graphs on the Dashboard


  • Firmware of the microcontroller on the HAT and the service agent on the Raspberry Pi can be updated remotely
  • Scheduling wake-up/shutdown time or routines
  • Creating e-mail alarms when a parameter exceeds certain thresholds
  • Battery capacity can be updated for a precise percentage calculation (2500mAh by default)

    Very high quality construction, good materials, and adequate installation instructions. A little lacking on some features (that I expected). Very good in terms of flexibility. Powers the Rpi LCD directly (if you use the solder pads to attach two wires). The (offline) Python API is convenient and easy to read. I haven’t used the cloud system.

    The S1, S2, and 5V out all have solder pads that are very convenient to attach external components or circuits.

    The hat will charge the battery, power the pi, lcd, and all attached USB items without causing any sort of low power indication on the Rpi. It is very powerful. In cases of very high power usage, it will use the attached power and discharge the battery, keeping the Rpi powered at all costs. Minimum time I get from a 18650, alone and unplugged, is at least 40mins, but my power usage is high with my setup. YMMV

    I would like to see certain features that *do not currently* exist.. Immediate power on, voltage threshold power on, and safe shutdown as soon as power is removed. 3 simple things *that this does not currently do*. These items are the only reason it does not get 4 stars for me personally. It has great features and seems to be getting regular firmware and API updates that add features.

    4/5 overall, but I’d give it 4.5 if I could.

    I am super-impressed with the sixfab UPS hat. It is extremely well-made and was very easy to setup. I am also impressed with the cloud-based control app, and while it’s overkill for my particular use case, it has opened up a couple of other use cases for me for future projects.

    I was a little disappointed that I couldn’t directly connect a larger battery pack directly (FAQ says so, even though you could technically plug one in), but I knew that going in. However, now that I have it up and running, I may not need it for my application, as the single cell powered my setup for around 75 minutes with light usage, and the battery was at 35%. That was very impressive, and far exceeds what I was expecting. Also, there’s plenty of available power options for this, so my design can be more flexible.

    Overall, a great little device, and a fantastic all-in-one power solution for maintaining uptime for a project. Well done sixfab engineers!
