USB Port and External Powering

8. USB Port and External Powering
The USB port on the Si5xxUC-EVB utilizes a micro-USB connector that is located on the left edge of the board on bottom side. A 2
meter micro USB cable is provided with the EVB kit. Any micro USB cable can be used that supports full USB connectivity.
If powering the EVB via the USB port, make sure switch SW5 is in the "USB" position. If properly connected to a live USB port, the
green VBUS_5V should illuminate.
If powering the board via an external +5V power supply, make sure SW5 is in the "EXT" position. Once +5V is connected to the board
via the +5V_EXT connections, the green +5V_EXT LED should illuminate.
