12v relay board Customers Reviews

  • Excellent relay module for quality and price.

    posted by EdTronique

    I have spent some time using much more expensive computer controlled modules in the past that were similar to this but this one channel relay module beats them all for quality to price ratio. This single relay channel can easily be adapted to most computer interface to control remote things such as opening / closing a garage door, controlling lights and can also be easily controlled by an Arduino or Raspberry PI. Easy to configure and control with any most PC programs or with an Arduino.
    Great singlechannel domestic voltage control module. Including a one page manual of operation could be a welcome addition - for $.50 cents extra if needed.
    Excellent unit built superbe quality for its affordably low price.
  • Original piece

    It is an original Arduino product. Good assembly and all inputs and output are labeled. It arrived safelly packaged in a bubble bag inside a carton box. Low price.
    I think that is a good buy.It can be useful for another electrical circuit, although arduinos
    I would buy another if i need it because of it reasonably price.You have the security that is an authenthic product.
  • A nice little relay module

    The price is good and the module reliably does what it's supposed to. The circuit that powers relays is galvanically separated from the input pins via optocouplers. Very easy to use with any microcontroller.
    It is good for a home automatisation. I am making an Arduino-controlled timed switch for my terrariums and aquariums, for turning lights and heaters on & off during a day cycle. For me, 8 channels is kind of too many, a 6-channel module would be fine, but DX doesn't sell them.
    If you need to control several 230V powered devices with a microcontroller, buy this.
