The Relay Module provides a solution for controlling high current devices that cannot be controlled by the Arduino’s Digital I/O pins due to their current and voltage limits.
The Relay Shield features four high quality relays and provides NO/NC interfaces, four dynamic LED indicators to show the on/off state of each relay, and the standardized shield form factor to provide a smooth connection to the Arduino board or other Arduino compatible boards.
Arudino Uno/Leonardo compatible; Other board or micro-controller via jumper cables.
Interface via digital I/O pins 4,5,6, and 7
Relay screw terminals
