  • Extremely Versatile and Fantastic Range

    posted by GreginOtago

    Has three different types of operation, select-able by a pin switch. This provides great versatility with the two buttons on the Remote. Remote has a huge range - I have it operating flawlessly over 50 metres to the receiver, which in inside a steel box and located behind a small berm (although the receiver's aerial is located inside a small waterproof plastic cap located at the end of the metal box - still impressive though!)
    So good, I ordered a second one.
    Very good value for money.
  • Really nice relay controller

    posted by Cimistus

    Looks really well built. USB side is quite well insulated from the relays, so using even high voltages shouldn't be a risk.
    Suitable case may be an issue, but then again, DYI cases are plenty. Also a little bit of searching and I found linux software too ( https://github.com/davidbuechi/UsbRelay ). Board also seems to have external +5V input possibility, which propably makes it possible for the relays to keep their state even if controlling computer is shut down - haven't tried it, though.
    Nice little USB controlled relay board for whatever you want to control.
  • good, high quality item

    sturdy design, remote switch casing is even made of metal
    don not know long time survival of this item, regarding build quality I think it's good. Expect to use a 12V power source, an abandoned charger / power supply will do
    perfect for non critical doors, don not use these openers if you want to be absolutely sure
