Involvement Level: Expert (understands the inner workings)
Pros: Standard 4-channel relay board. Has transistors for the relay coils, and flyback diode protection. Relays close on HIGH signal, just as you would expect.
Cons: Poor quality through-hole soldering. Some components crooked, flux residue left on board -- you probably want to wipe this off with alchohol when you get it.
Other: Not sure what more I can say about it? It's a standard 4-channel relay board.
