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

Package contents

• 1 x PiRelay HAT
• 2 x Standoffs
