Description
Shield to drive up to 8 relays from Arduino
Just 2 I/O pins required to control 8 outputs
Output current (Maximum): 115mA per channel
Pre-fitted stackable headers
The 8-Channel Relay Driver Shield drives up to 8 relays from your Arduino using just 2 I/O pins. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs. Includes back-EMF protection and works with a wide range of relays. Perfect for home automation projects. Maximum output current per channel is 115mA, which is plenty to drive common relays. For larger loads you can use this shield to control FETs or solid state switches.
Features
Plugs straight into your Arduino-compatible board
Individual LED status display on every output channel
LED status displays for host power and external power
Drive relay coils of 5V to 24V (with external power supply)
I've used a bunch of these, mostly for driving 12V LED bulbs for SuzzoHapp push button back-lights. Great for when PWM isn't needed and saving pins is. For one project I used two of them attached to one Arduino (selectable I2C address is great). Love them. I also appreciate the status LEDs. If I don't have 8 things to drive, I'll often use the extra status LEDs to show the status of other things. I also love the "N-Drive Shield" when I have 6 or less things to drive, pin usage isn't as critical, if I need PWM or more current.

Very Handy Board!
