Relay Module 3V
BD 7.500
The Relay is a digital normally open switch that controls a relay capable of switching much higher voltages and currents than your normal Arduino boards. When the relay is switched on, the LED will light up and the relay will allow current to flow. The peak voltage capability is 250V at 10A. With the help of the Grove System, engineers and makers can easily avoid jumper-wires problems.
