Relay Shield V3.0 For Arduino

Part number: 103030009
Description
When you need to control high current loads to your Arduino / Seeeduino boards, the Relay Shield with its four advanced relays is the answer. Delivering a NO (Normally Open) / NC (Normally Closed) interface and featuring four LED indicators to show the state of each relay’s on/off state, you could also use this versatile shield to control devices that can’t be controlled directly by Arduino’s Digital I/Os. On top of all this, standardized shield form factor gives a smooth connection with Arduino and compatibles.
