  • Good for Proto and maybe production

    posted by TimTheEngineer

    - Includes screw through mouts for mounting to a chassis or project board- Very cheap to include two relays, PCB, headers, and driver circuits.- Very simply wiring because of screw terminals- Does come in a small anti-static bag
    If you can run a meter and need a simple 2CH relay circuit you would be hard pressed to build this for less not to mention the time it would take.For a Proto it's a no brainer, buy two.
  • Solid piece of kit

    posted by mattura

    A good quality build, which is solidly constructed. There are LEDs to show power and when each relay is switch on. It has a nice 'click' when the relays toggle. It works out of the box with arduino nano and other devices I'm sure. You can connect to outputs Normally Open or use the other slot for Normally Closed
    Also good that four screw holes are drilled to attach it to something.
    A good cheap set of 4 relays, easy to connect and use.
  • Easy to use

    Very easy to use. A good option for people who want to start with domotic services. A good option for people who are using a Raspberry Pi like me.
    Very nice for the price. Everyone who likes working with low cost electronic should give it a try. Very nice presentation. Leds make us know if everything is working ok.
    Happy for the bought.Resumen para los hispanos:Producto de buena calidad a un bajo precio. Los tiempos de envío son francamente buenos. El sistemas es una buena opción para usuarios de Raspberry Pi o Arduino. Incluye 3 leds para indicarnos el estado de funcionamiento.Estoy bastante contento por la compra.
  • 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.
  • 2 Channel 5V High Level Trigger Relay Module for Arduino

    posted by Troncs

    The value is low compared with other modules of the same segment, ie 5v input with 2 relay, 28v to 250v supports in a strain of 10A.
    Can be used with a switch in parallel. Easy installation for aqules who has basic knowledge of electronics and arduino. This relay will serve 95% of the projects, taking due attention to the engines pscina.
    Plate of red and blue relay. The circuit comes with an opto-isolator which very important for this type of connection.
