ThePower + Relay HATis designed as an all-in-one simple automation add on for the Raspberry Pi. It combines the beefy 5V 3A power supply from our series of Raspberry Pi Power HATs with two 10A relays.

These are ideal for situations where 7-16V DC power is readily available and higher voltage / current loads need to be switched.

Please note that whilst this can technically power a Pi 5, it does not offer the full 5A required to make the most of the board. Fine for projects not using USB devices or powering other things from the 5V line, but not ideal for more demanding builds.

To add to the functionality, we have also included a pair of Adafruit STEMMA QT / SparkFun Qwiic sockets so additional Qwiic / STEMMA QT sensors and breakout boards can be added with ease. To support the additional load on the 3.3V bus, there is also an independent 3.3V regulator to power the bus.

This HAT is compatible with all 40-pin models of the Raspberry Pi. The relays are triggered with GPIO 4 and GPIO 17 on the GPIO header. The board is fully assembled with a Raspberry Pi GPIO header, meaning no soldering is required for this board!

We also offer a smaller single relay version of this board for the Raspberry Pi Zero. Check out the full BCRobotics range here, including dedicated relay HATs and more!
