    4.0 out of 5 stars works well on Raspberry Pi, best on 5V pin, avoid 3.3 V

    4.0 out of 5 stars works well on Raspberry Pi, best on 5V pin, avoid 3.3 V
    Reviewed in Canada 🇨🇦 on May 2, 2022
    I used this relay on a custom build arcade, to allow my Raspberry Pi to turn on/off the monitor and marquee lights during boot/shutdown (110V, only around a couple Amps total). Initially I had use the 3.3V pin to power the relay but the result was that the relay switch worked unreliably. Sometimes it worked, sometimes it didn't - it seemed to "stick". After I reconnected it to the 5V pin, it worked well.
