Seeed Studio, Relay Shield V3.0

The Seeed Studio relay Shield provides four high-quality relays that can control high current loads to Arduino/Seeeduino boards. This module operates on a supply voltage range of 4.75V to 5.25V and the current range of 8mA to 250mA. It also provides NO (Normally Open)/NC (Normally Closed) connection interface. It can be a good solution for controlling devices that cannot be directly controlled by Arduino's digital I/Os. This module has a standardized Shield form factor that enables smooth connection with Arduino and compatibles. The Shield also has four LED indicators to show the ON/OFF state of each relay.
