  • Great little gadget

    posted by mtrcek

    The board is great. Powerful enough, it is small and compact switch mode power supply. I have used it as a LED stripe driver (for 1m of LED stripe) and as small audio system power supply. For the last one - it is very quiet, the EMI circuit does it's job. The holes make it easy to install.
    None
    A very good and usefull SMPS. I really recommend it.
  • Easy to use device for separate your micropocessor from the rest on circuit

    posted by richardfabo

    It's easy to use, when you know, where should be connected what. It comes without scheme, but connection is easy:VCC + GND = +12V DC and GNDIN1 .. IN4 = your 5V outputs from microcontrollerCOM = your GND from microcontrollerGND = the same as 12 V GNDNote: there is a jumper for connecting COM (=microcontroller GND) and GND (=12V source GND), to have the same potential. But this is not needed, when disconnected, the circuit of microcontroller and other 12V circuit are isolated (unless there is any other connection)...Other pros: red LEDs showing state of relais (on/off), one LED is ON when 12V DC supply is present.
    It solid and good contruction, also soldering is nice and proper. The faulty relay can be easily replaced.
    Worthy to buy.Cheaper than buy the parts anf build by yourself.
  • Faulty regulators

    posted by arcomri

    For the working one:- simple to use 3,3V regulator- more than enough power capability for most of your projects- breadboard friendly
    Received 5 of them in a nice antistatic bag but pinned down on a piece of styrofoam (!). End result: 4 out of 5 were dead on arrival (output voltage was the same as the input voltage). Maybe it would be a good idea to reconsider the packaging method :-)
    Simple and useful little 3,3V regulator for on-the-fly projects. Handy to have around.
  • Very cool button

    posted by queensoft

    Very good quality, strong build.Product image is excellent, colors are very bright, exactly like that.Each connector and wire has different color and text (HDD LED, Power LED, Power SW, Reset SW).All parts are included:- power button, very long cable- one small philips screw- one small metal bracket, for the back of the computer- one round stick pad, to place the button wherever you wantVery easy to install, each connector fits exactly on the motherboard.Cable is very very long, you can put your nw fancy power button whereever you want.
    Very cool item, product image is very good, exactly like product.Reset button is pretty small.This could be a good thing, you don.t need to reset your computer by accident.
    Excellent, I would recommend it to all my friends.
  • good product

    posted by fnflores

    good quality product, great luminosity (please take care, do not see LED directly), easy to use, it is applicable for any Arduino LED project, it comes with a standard packing.
    Recommended for high luminosity LED projects (I did a Christmas light for home), also to test any Arduino library works fine!
    Use it! it is fun and really easy to use!
