Unpowered early review May 1, 2020 By: Stephen Young from Vancouver, BC Canada   Nice and compact quad module.  A nice touch is a mechanical isolation between the output commons (the relays are Form C / SPDT) and the coil pins, via a PCB cut-through.  Another level of isolation is electrical, you can have a different 5VDC feed to drive the relay, but the DC Common is always common, so not a fully isolated set-up, i.e., keep them power supplies clean and them DC Common lines thick and intelligently routed. Another good thing about the board are the indicating LEDs, nice touch.  4 mounting holes, a bit too near the components? Full disclosure:  I have yet to power them up. Was this review helpful?

Great buy! Used w/ Particle Photon March 15, 2018 By: Christopher Uribe from San Diego, CA United States   I'm using this to route power to several solenoid valve's that intelligently open and close to allow water to run to my tape irrigation for my vegetable garden. I have four zones that have been happily watered and it was all thanks to this 4-Channel Relay Module. Thanks, Addicore! Was this review helpful?

good quallity relay board December 4, 2015 By: steve marciante from Williamsburg, VA United States   I have not had time to test it yet but it looks like a well made unit. The build quality and component selection are very good. Board layout is excellent and includes routed trace isolation, control single isolation, LED indicators and flyback diode for each relay. Good quality soldering and neat construction. What is really great is that all the connection terminals are clearly indicated. Although there is no actual datasheet for the board, the Addicore web page for this item has all the info you need Was this review helpful?
