power module 12v Customers Reviews

  • simple but good sound quality

    posted by CHANDRA66

    - works from 7V - 12V DC- starts with the last played song- good sound with high quality speakers- reads many different USB-sticks- combined on-off/volume switch/poti - line-in connector on board
    Nice to combine with bluetooth-audio module connected to the line-in.I made a wodden case with Visatone speakers and the sound is really awesome!
    It's really worth the money, anyway you need additional good speakers, a power supply and a heat sink.
  • Nice!

    White Light.Nice case finish and build.Good current specs.Wide voltage range of operation.@12V DC, 190mA measured.@5V DC, 290mA measured.No noticeable change in brightness from 5-14V DC.Self regulating, no external resistor or driver needed.
    This is a very nice led package for the price. Attractive finish and well built appearance. It has even light distribution for most of it's cone. Runs very slightly warm to the touch at 12V.
    Good value with nice light color. Will buy more!
  • Great little gadget

    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

    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.
