Many people asked if we did a "normal" style relay, a version that required just a single "data" line to turn on/off.
So we designed this.
You need 5v to power the relay coil (4v to 6v will do). The input (IN) requires just a few milliamps at anywhere between 2.5v and 12v. You can even use the same volatge you are powering the coil from.

I've used these relay boards in a Home Cinema installation to operate from the 12v Trigger output of a surround processor. Perfect - could do with a 12v supply option, but not a problem.

The kit was easy to assemble and even with my poor soldering skills I ended up with a functional board. I'm very happy with it.
