relay module board Customers Reviews

  • Works great with Arduino

    posted by GreenTechNetwor

    So far, this module has been great for use with my Arduino. I've had no problems getting it to work. In addition, the soldering and circuit board seem to be of rather high quality.
    This is another great cheap module to add to your Arduino for a learning experience.
    These are great for controlling an external device that uses relatively high current. For example, you can set this relay up to switch on a light, stereo, etc. Anything up to 10A, and this relay can handle.
  • Good product at a very interesting price

    posted by Ferraldo

    The main advantage of this product is that the input is optically insulated. This is particularly relevant for me as I need to connect the board to an expensive National Instruments I/O board. Beside this, the product is cheap, compact, and reasonably well assembled. It has good connectors and useful status LEDs.
    The board is packaged in an antistatic bag.
    Almost impossible to find this quality at this price.
  • simple and functional

    Holes in the corners make this item easy to mount, and pins will ease connections with our arduino projects or homemade circuits.
    This item is easy to understand and very helpfull to use in amateur/profesional projects. Made myself a neat clap clap switch.
    Handle with care! Avoid working with high voltage -develop your project first, connect afterwards. Mount firmly if you don't want hazards.
  • Good price but lower quality

    posted by Andrebureau99

    Very good price, low foot print, can be put to use with arduino or other type of CI. I like the way the inputs of the relay are on terminals, can be installed on standard small metal stands. Because of the price I prefer to use this unit unstead of a multiple one so if I had to make a change it's not a big deal. For myself I like the color it add to my project.
    Still, will purchase again but always two units or more so I can accept to have one defect.
    Nothing for now.

    Good quality. The first delivery had one non functioning relay. After 2 weeks I received a new board without any costs: great service Deal Extreme !!
    I'll buy some more of these in the future.
