MASTER DEVELOPMENT SYSTEM
The SG Series Master Development System provides all of the tools necessary
to evaluate the SG Series GPS receiver module. The system includes a fully
assembled development board, an active antenna, development software, and
full documentation.
The development board includes a power supply, a prototyping area for custom
circuit development, and an OLED display that shows the GPS data without the
need for a computer. A USB interface is also included for use with a PC running
custom software or the included development software.
The Master Development System software enables configuration of the receiver
and displays the satellite data output by the receiver. The software can select
from among all of the supported NMEA protocols for display of the data.
Full documentation for the board and software is included in the development
system, making integration of the module straightforward.
