Great little relay boards!

These relays work great for my application. I had to turn on and off a switch shutter for one device, a 5VDC signal for another, and 110VAC for others with an Arduino Leonardo. All channels on both boards are working properly. The only quirk is that they need a "high" signal in the NO/NC position due to the optocoupler. A "low" signal activates the relay.
