## Description

The PiRelay V2 is a Raspberry Pi relay add-on board that 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](https://core-electronics.com.au/raspberry-pi/boards/model-b.html) 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 **30VDC/10A**.

### Features

- Control 4 appliances
- Octocoupler
- 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
