  1. Review by Craig verified purchaser

    Great little unit - cheap and versatile. (Posted on 30/07/2018)

  2. Review by Trevor verified purchaser

    A useful relay module for projects that only require 2 relays. Great service from Core Electronics team as usual. (Posted on 14/05/2018)

  3. Review by Ron verified purchaser

    very useful self contained module (Posted on 19/03/2018)

  4. Review by Nathan verified purchaser

    Awesome little board! Great value, turns out at low voltage (am using it from a PIC programmed at 3.3V), and opto-isolator is great. Documentation is a bit scarce, but thanks to Michael above for the link to the schematic (input pins need to be pulled low to trigger.. and am pulling up to VCC via 10K)

    The schematic file/project has moved to github, and after poking about, found it here:

  6. Review by Lee - Nice Relay verified purchaser

    To use with a 3.3v board - remove the blue jumper, connect 5v to JD-VCC and GND on the left, 3.3v to VCC on the right and your output ports to IN1 and IN2. No need to connect to GND next to IN1. (Posted on 31/01/2015)

  7. Review by ROB - Value for money .... verified purchaser

    Relay is controlling 1150w Blower Pump and a 3w solar water pump for an outdoor spa ... it never fails ..

    perfect product .... yet another great product Core

  8. Review by Luke - Great

    Great little relay with a safe opto-coupler protected circuit. Also works on 3v3. Can't fault it. (Posted on 17/12/2013)

  9. Review by paul - works fine

    Seems well made and is neatly put together. It's optically isolated which is good and has led indcators when relay on, I'm using with an arduino, works as expected. (Posted on 4/12/2013)
