    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Workd, Have taken a lot of beating while beeing used in a PWM mode by error, but doesnt show wear even after what propably has been 1000 rapid on and off switches. DO NEVER USE THIS IN PWM MODE; THIS WAS AN ERROR FOR ME; IT WILL RISK TO TAKE FIRE LED is nic...
    Cons:
    The mounting holes are a bit to close to the electronic to be sure to avoid shorts because of the screw head tuchng the tracks....

    Really good and cheap relay module

    posted by kasperk on 05/28/2014 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    * Does exactly what you expect a relay to do * Works perfectly together with Arduino * Mounted on a small board which is prepared with mounting holes
    Cons:
    I haven't found any cons yet. I suppose the bright LED could bother some developers or users, but that can barely be considered...

    Works also with Raspberry Pi

    posted by marki555 on 05/12/2014 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Works also with Raspberry Pi, which has 3.3v logic. Just connect "+" to RPi 5v rail, "-" to RPi ground and "S" to any RPi GPIO pin, which is 3.3v and is configured as output. The board has a transistor which uses the S pin (3.3...
    Cons:
    none found :)

    Good relay

    posted by otrofox on 07/22/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    It comes with a little board that makes is more robust. Screw connectors for output also facilitates the wiring. Breadboard connectors for controlling also help usage.
    Cons:
    It should be nice to use just two wires to control the relay (Signal - Ground) but three are needed (Signal - 5v - ground) Alth...
