This little board is pretty much a common sense connect and go issue. The schematics look to be for an 8 channel relay board, but you can read between the lines I guess. I new person may get confused however.
The cheapest relay modules.
I tried it whit my Arduino to control the light of my house. The only problem was that it wasn't well protected and the PCB have a hit in one of the holes. In spite of this I recommend the buy.
Works great with linear actuators that require almost 10 amps. Most relay board are rated under 5 amps and cost way more than this one. LED's on the board helps to debug without actually wire any device to it.
Le moins cher des modules à relais.
