Arduino 4 Relays Shield

The Arduino 4 Relays Shield allows your Arduino to drive high-power loads.

The Arduino 4 Relays Shield is a solution for driving high power loads that cannot be controlled by Arduino's digital IOs, due to the current and voltage limits of the controller. The Shield features four relays, each relay provides 2 pole changeover contacts (NO and NC); in order to increase the current limit of each output the 2 changeover contacts have been put in parallel. Four LEDs indicate the on/off state of each relay. Getting Started You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics. Power

The shield doesn't need external power: it will be provided by the base board, through the 5V and 3.3V pins of the Arduino board used as a base.
