    I presume you mean USB cable; Bluetooth is wireless!

    I found that board on Ebay, it requires 10 to 18V power. It is not surprising it does not work on. 5V USB port.

    Sir Azuro . . . . .

    Megaditto . . .also . . . . on . . . .that aspect of
    I connected a bluetooth cable . . . .

    HOW . . . you do dat ?

    As I can only see the foil patterned, ,receive antenna built on the board, that is being just adjunct to C7 surface mount capacitor.
    Then there is only the central power connector and output speaker connections on either side of it.

    Bob, it is BT you can even see the antenna on the input end of the board

    @Azuro so I assume you have the matching BT (Bluetooth) transmitter board for this unit ?

    I didn't say there was no bluetooth, just thst bluetooth does not use a cable.

    I am guessing he plugged it in to a USB port for power, and 5V is not enoigh since itrequires 10.
