This 3-Channel Relay Module HAT is a smart expansion board designed to fit directly on top of a Raspberry Pi. It allows the Pi to control up to three high-voltage electrical devices such as lights, fans, or appliances. Each relay is opto-isolated for signal protection and can handle up to 250V AC or 30V DC loads. The HAT features status LEDs and uses GPIO pins to receive control signals from the Pi. It is ideal for smart home applications, IoT projects, and other automation systems where compact and reliable switching is required.
