The EVK1104 board can be powered from 3 different sources, external power supply,
“USB VCP” and “USB USER” connector. If two power sources are applied at the
same time the following priorities are used to select the current valid power source:
That means that if an external power supply is connected to the board, it has the
highest priority and will therefore serve as current power supply. Other power
supplies that are connected to the board at the same time will be ignored.
On the PCB revision 1, the external power supply must be 5.5V. In order to be able to
supply external USB devices that are connected to the board the minimal power
supply specification should be 5.5V, 1A. This ensures that the board will work
properly if a USB device is connected that needs the maximum allowed 500mA as
specified in the USB specification. It is not possible to draw that amount of current
from the host through a normal USB cable but there are cables available that can be
connected to two hosts (such a cable is not a kit content).
When playing music from a mass-storage device, it is enough to power the board
from the USB VCP connector. Use the “Mini-B plug to std-A plug 1.5m USB2.0” cable
that is included in the kit and connect it between the host and the board USB VCP
connector.
