The Relay Shield utilizes four high quality relays and provides NO/NC interfaces that control the load of high current. Which means it could be a nice solution for controlling devices that couldn’t be directly controlled by Arduino’s Digital I/Os. Standardized shield form factor enables smoothly connection with the Arduino. The shield also has four dynamic indicators show the on/off state of each relay.

 

 

• Arduino/Seeeduino compatible
• Standardized shape design
• Working status indicators for each relay
• High quality relays
• Provides NO/NC interfaces
