host, the use of an external USB power supply which is able to deliver higher currents than 500 mA is strongly
recommended.
After power-up the green DEBUG LED starts blinking. When there is a connection to a PC via the Debug USB
plug X101 and the USB Debug Device drivers are installed on this PC, the DEBUG LED will turn from blinking to
constant illumination.
