Interface Applications
3.1. Micro-USB Interface
The main power is supplied via a Micro-USB interface. Both Micro-USB and SD card interfaces can be
used for data communication, and they can be switched to each other by the alternation switch (S301). If
SD card interface is used for data communication (NMEA sentence output), then both SD card 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 sentence output, during which only a USB cable is
needed.
