Documentation and support unavailableReview by Vernon
(Posted on 2/8/14)

Purchased this item last summer and was unable to get it to work.. Spent hours searching for documentation and support, but no help available. Posted in forum in July. Only one response, from person unable to solve the same problem. Reposted problem recently, no responses to date.Essentially I can get the leds by the relays to light up, but the relays do not change.

Excellent boardReview by Bruce
(Posted on 12/24/13)

I'm using this board with a Raspberry Pi to control a Christmas light show. It works brilliantly. The switching speed of these solid state relays is amazing, and being solid state there isn't a "click" every time one fires. The board is labeled clearly, so anyone with basic electronics knowledge should be able to wire it up in a minute flat.

It’s no exaggeration to say that the products of Sainsmart are good, I have bought many
things here, I do like it!

not badReview by eswuh

The board is constructed pretty well and for the price I was surprised to find that every relay (I bought two boards) was working flawlessly. I only have one complaint. There was one loose solder connection on an output terminal that would cause the light on that relay to flicker. In general, it's a good product.

relay moduleReview by bvcsr

Good build quality. Good soldering and component placement. I think the relays might be on the light side for switching heaters or motors that have a high initial current draw. All in all, it's an excellent product for the price.

Thumbs up! Review by jhguig

Does exactly as expected and actually much smaller than I expected. Good build quality.Work like a charm and are the best value on the internet.

Pretty board, no documentation.Review by Kov
(Posted on 5/8/12)

The board is well set up and pretty easy to work with if you know what you are doing. The downside is that it does not come with any documentation, so unless you can figure out how to use the board from the info on this page, you may have a hard time with the board.
