SainSmart 8-Channel Solid State Relay Board for Arduino UNO MEGA R3 Mega2560 Duemilanove Nano Robot

Description of product does not say that it can only switch 75V AC or more. I needed to switch 12V DC and so these were no use.I do not know if the product is a good one or not, I have rated the product low due to the lack of info in the description, this info is not even in `product details` but lower in the extended information.

You look at a board and assume it works one way... and then you get a loud snap and a cloud of magic smoke. Always read the schematic. Other than that, works brilliantly (I bought a second one after realising my mistake). Well put together bit of kit and at a great price.

Great but remember that these are only good for AC power (e.g. mains) and no good for 12V DC for example

This product is excellent value for money. It performs exactly as described and I have now used it for several projects with no problems at all.

This relay board is well built and works well with the Raspberry Pi or Arduino kit.Highly recommended for anyone looking for 8 channel relay control.I have only had this working for a few days but so far so good. (Switching lights)Also remember the relays are good for switching a maximum of 440Watts at 220V.So don't go switching your kettle or microwave as it will burn out!Overall I would definitely buy another one.

Well built board, exactly as specified.
