EVB Interfaces

3.1. Micro USB Interface

The main power is supplied via the micro USB interface.
Both micro USB and UART interfaces can be used for data communication, and the two interfaces can be
switched by the alternation switch S301. If UART interface is used for data communication (NMEA
sentences output), then both RS232 and micro USB cables are necessary for operating the EVB. So it is
strongly recommended to use the micro USB interface for both power supply and NEMA sentences output,
during which only a USB cable is needed.

NOTE
If PowerGPS tool needs to be used, then it is recommended to use the UART interface for data
communication.
