Grove - Relay High current 5V/10A small 1-way mechanical relay switch Arduino

The Grove-Relay module is a digital normally-open switch that can handle the current up to 5A at 250VAC for long periods of time. 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. It is widely used in remote control, telemetry, communication, automatic control, mechatronics, power electronics and other fields.
