dc usb module Customers Reviews

  • 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.
    none
    I'm with my a month ago and so far work. I liked the price, and also the result. A great deal, no doubt.
  • Very nice module

    Works with a 3.3V power supply . Two power amps similar to TS4990 deliver 500mW per channel in BTL on 8 ohms load .
    Sensitive radio but with tendency to intermodulation . Don't use a long antenna if you have powerfull transmitters in close vicinity .
    No problem to read USB keys and SD cards
    6 equalization modes for amateurs !!!.
    Quality control of the manufacturing to enhance (no IR receiver !!!)
    Overall a very good module , small , easy to use .

    - It has good stabilization of the output voltage. When i have supplied it with 12V the output stayed constantly at 4.99 - 5.03 volts regardless of the output current which was between 0.5A to a maximum of 2 Amps
    - A small switch would be a good addition to it when using in the car, or at least connecting it to a switched plus is a good idea to prevent it from running idle and flattening the battery.
    Very good DC power supply, with stable voltage. The price could be better though.
  • Good mp3 player with remote

    posted by H3PO4

    +good quality of soldering on mine (which is not always guaranteed)+good sound (really low noise levels)+small footprint of the PCB, can be easily integrated almost anwhere+good description of connectors on PCB+wide input voltage tolerance
    you have to understand at least basic electronics to make this work, it is not exactly "plug and play" - you need to connect an amplifyer etc...- the user interface for navigation no your USB is sparse - but it did not matter for mine implementation
    If you would like to get good mp3 USB player with remote and know your wires and soldering, you cant really go wrong with this one.
  • Great product!

    Small but fully functional unit. Great gadget. I plan to implement this into amplifier. Good thing is that all connectors are properly labeled.Two weeks delivery time with free shipping!
    I just tried this product, and I have not spent much time with it, but I can already see that I will have a lot of fun with it.
    All in all i was very satisfied with this product and would recomend this seller to anyone.For this price you get a very nice and useful gadget.
