This does not explain how to connect the 5vdc power to the card. Do you use a cable from the raspberry pi's power or do you need an independent power supply? what kind of cable is required for the power supply? What plugs in to the USB connector, is it power supply, if not the headphones or mic. If it is power supply why is there another power supply input connector?
