UART Interface

20B
The UART interface (highlighted in Figure 6 below) is provided via the micro-USB connector.
The UART interface is used to trace NMEA messages and to upload binary
Before using Silicon Labs' CP2104 UART-USB bridge chip located inside the
unit, install the Virtual COM Port (VCP) driver. The driver can be downloaded from the
Labs (Silabs) web page:
https://www.silabs.com/documents/public/software/CP210x_Universal_Windows_Driver.zip
The VCP device drivers allow the CP2104 device on the
PC's application software as a standard COM port. Application software running on the PC
accesses the CP2104 device as it would a standard hardware COM port configured
Table 1. Data transfer between the PC and the CP2104 device is performed over the USB
interface.

GNSS Input Antenna

21B
GNSS input is available through an SMA female connector, highlighted in Figure 8 below.
A passive or active antenna can be used on the PNT-SG3FS-EVAL.
The DC power supply for active antenna is 3V3 with current limitation in case of a short circuit.
