    This is the relay I needed and I bought 5 so now I have extras. It's an exceptionally good deal. The boards are very small and screw terminals on power, input and the relay contacts make it easy to connect and disconnect. Don't pay extra for tracking because the tracking isn't properly updated. Just be patient and expect the shipping to take at least 3 weeks.

    Good quality product, the packaging should only be safer, since everything came in a bag.

    5 stuks besteld en geleverd gekregen. Zaten goed verpakt. 1 reeds gebruikt, de andere zullen het ook wel doen, ik heb er vertrouwen in. In mijn schakeling wordt het relais ingeschakeld door een Arduino Uno, werkt prima. Je kunt met een jumper instellen of het relais moet inschakelen met een LOW of een HIGH. Er zit een groene led op de print om aan te geven dat er voedingspanning op staat en een rode led die aangaat als het relais ingeschakeld is. Ziet er allemaal goed en stevig uit. Ik ben tevred

    These are great little 5V relay modules, which offer a lot of features for the price. High or Low logic trigger, Optical isolation, so you can drive it right from your microcontroller, and both NC and NO contacts. Considering that you can use them to control low-load Mains voltages, I'm pretty impressed!!

    haven't had a chance to test the relays yet, but I intend to build a raspberry pi based network controlled power outlet. so I can switch systems on and off remotely - a nice case with 5 outlets / channels - good value for money.
