Look good and it has a good price
Arrived and sealed perfectly ! Awesome for wifi and bluetooth projects
Solid and well made product
Good relay. I drive it off 15 volts (I couldn't get a 12 volt trigger signal) and it has no problems with that. The documentation of this module could be better, but hey, everyone who buys this has at least some experience with electronics so it isn't that big of a problem! There was only one thing that confused me a bit. on the picture there are just normal pins for the trigger signal, but in the module that I received it were terminal blocks.
Recieved 3 weeks after ordering on my door in Athens, Greece from local post office. The item looks good, as the photo. Solders and pins are ok. I will try later but I am pretty sure there is no problem.
Products as described.
They work perfectly
Good and simple relay. Thanks BG!
Simple and good 😊
