Introduction
The Relay Shield is an Arduino compatible smart module with 4 mechanical relays providing an easy way to control high voltage. The max switching power is 35VDC 70W for each channel. It can be directly controlled by Arduino through digital IOs with external 9V DC supply. With the XBee form socket and 315/433MHz RF module interface, the Relay shield can be remotely controlled, making it easy to use in robotics, industry control, smart houses etc.
Note: Take care the pins on the Shield should not be touched with USB connector of Arduino UNO when they are connected .
Features
- Arduino, Arduino Mega compatible
