Description
The Raspberry Pi Power + Relay HAT is designed as an all-in-one simple automation add on for Raspberry Pi. It combines the beefy 5V 3A power supply from our series of Raspberry Pi Power HAT 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.
To add to the functionality, we have also included a pair of Adafruit STEMMA QT / SparkFun Qwiic socket 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 the Raspberry Pi A+, B+, 2, 3, 3+, 4, and all versions of the Pi 5. 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 make a smaller single relay version of this board for the Raspberry Pi Zero.
