5v module Customers Reviews

  • 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.
  • Surpassed my expectations.

    Easy to install. Low current draw. Built-in audio amplifier. Good audio providing you use a decent pair of speakers. (I'm using an off-the-shelf pair of bookshelf speakers and it sounds great).
    I'm thinking of buying two more for my kids.
    I'm glad I bought this.

    +The price is super low for this great product x2+I use mine with 3xAAA Alkaline battery, and it works flawlessly+Much more clean spot than may cheap lasers I have seen +Size is small enough for various purposes
    I bought these to modify airsoft LAM-unit into a real "laser aiming unit" and this sku was just the right bit fot that use! I can gladly recommend this for anyone doing something similar.
  • great relays, recomended for arduino

    posted by MaartenArits

    very good relay series, easy to use. just connect the ground and 5V and you are ready to go. by pulling down the appropriate pin a LED turns on and the relay switches. This ensures that your microprocessor or other control circuit will have minimal power drain.
    Great quality for that small amound of money!
    if you need 8 relays, this is the way to go!
  • For DIY projects

    posted by Debesis

    Small thing for DIY audio projects in homestead. Very good autonomy and simplicity. Playing USB, TF cards and radio so good how it cost. I played different types of encoding and bitrates without any problem. Maybe navigation on files can be improved, because of no folder splitting, but there is no manual.
    I'm with my a month ago and so far work. I liked the price, and also the result. A great deal, no doubt.
