Raspberry Pi 4 Channel Relay HAT
Need to drive high current or high voltage devices with your Raspberry Pi? This premium 4 channel 10A relay HAT can handle it! Each relay has the Input, Normally Open, and Normally Closed contact broken out to a nice 5mm pitch screw terminal. This HAT is compatible with the Raspberry Pi A+/B+/2/3B/3+/4 and uses GPIO pins 4, 17, 27, and 22 (Pins 7,11,13,15) on the GPIO header. Each relay driver is connected to the GPIO through a solder jumper and can be alternatively connected through the 4 pin 0.100″ header if a custom configuration is required.
This board does not ship with a header so minor soldering will be required before it can be used with the Pi. We recommend a Tall GPIO Header for this board.
As of September 14th 2017 we are now shipping version 1.1 of this board. Version 1.1 adds isolation routing to the board and a few SMD components have been shifted around. It is otherwise functionally identical. This board Works with all “A” and “B” versions of the Raspberry Pi (Pi A+, B+, 2, 3, 3A+, 3B+, and Pi 4)
Please Note: While this board is capable of switching higher voltages, please exercise caution. If you are inexperienced or unsure about how to use this product safely we recommend looking at the IoT Power Relay, which has all of its high voltage circuitry fully enclosed.
- Fits directly on the Pi's 40 pin GPIO header
- Switch up to 10A per channel!
