4 Channel Mechanical Relay Shield for Arduino UNO MEGA
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. No Hasle connection to Arduino UNO or MEGA.
Standardized shape design.
Working status indicators for each relay.
High quality relays.
Provides NO/NC interfaces.
Operating at 5V , direct driven by micro controller pin.
Note: please cover USB socked on Arduino board to prevent possible contact metalUSB interface casing with bottom of this shield.
Arduino UNO not included.
