  • This is a really nice board

    This is a really nice board to make a diy USB powered speaker driver. Powered from USB it probably doesn't use the full volume, as USB ports typically deliver between 100mA and 500mA, which is less than needed for max output. However, when using speakers that aren't really inefficient decent audio levels can be achieved. Since I love diy projects like these, I really like this board.


    The capacitor could be a little bigger, say 2000uF or more. But that's easy to do yourself if you know how to solder electronics.


    Get the polarity right to avoid damage to your USB port. Use a multimeter to be sure. There is no diode on the board to protect it from wrong polarity, which is actually a good thing since diodes lower the voltage, of which you need all... So just be careful with it.


    For thuis price, it's awesome.
