About this item

The 4-Channel Relay Shield is a plug-and-play module designed to interface seamlessly with the Arduino UNO, enabling control of high-power devices such as AC fans, lights, pumps, and motors. It features four onboard relays capable of switching both AC and DC loads. Each relay is triggered by a 5V signal from Arduino GPIO pins, eliminating the need for additional wiring or external circuitry. This shield is ideal for rapid prototyping and reliable operation in home automation, industrial automation, and robotics applications. Its compact design and straightforward setup make it perfect for controlling multiple devices directly from your microcontroller.
