PiRelay - Relay Board for Raspberry Pi
The PiRelay is a Raspberry Pi relay add-on board which provides a solution for controlling high current/voltage devices and makes your home appliances intelligent.
It's a nice solution for controlling devices that can't be directly controlled by the Raspberry Pi's Digital I/Os (GPIO). The standardised HAT form factor enables a smooth connection with Raspberry Pi.
The board includes indicator LEDs for easy debugging and can switch loads of up to 240VAC/7A, 125VDC/10A.
Features
- Control 4 appliances
- Relay status indicators
- Compatible with Raspberry Pi 4, 3B+, 3, 2, Zero
- 40-pin stacking header
- Control PiRelay through PiRelay mobile app
- Make your home IoT enabled

On the board
Specifications
- 4 High-quality relays - loads up to 240VAC/7A, 125VDC/10A
- Standardized HAT shape and design
- LED status indicators for each relay
- 40-pin stacking header for accessing GPIO
- Connectivity of the Relay with Raspberry Pi without GPIO
- Pin 2-> 5V
- Pin 6->GND
- Pin 7-> Relay 4
- Pin 11->Relay 3
- Pin 13-> Relay 2
