SG Series Master Development System User's Guide
INTRODUCTION
The Linx SG Series RF modules offer a simple, efficient, and cost-effective method
of adding GPS capabilities to any product. The Master Development System is
intended to give a designer all the tools necessary to correctly incorporate the SG
Series into an end product. The development boards themselves serve several
important functions:
• Rapid Module Evaluation - The boards allow the performance of the Linx SG
Series modules to be evaluated quickly in a user's environment.
• Design Benchmark - During the design process of your product, the boards
provide a known benchmark against which the performance of your own design
may be judged.
• Application Development - An on-board prototyping area is provided to allow a
designer to develop applications directly on the development board. All signal
lines are available on a header for easy connection to the designer's circuits.
The Master Development System includes 1 assembled development board, 2 SG
Series receivers*, one SH Series antenna, 4 AAA batteries, and full documentation.
*One part is soldered to the board, one extra is for use on your first prototype board.

Page 3: Initial Setup
INITIAL SETUP Unpack the development system and install the AAA and coin-cell batteries. Connect the external GPS antenna. The power switch can select between the battery pack / DC power jack or USB if the board is plugged into a USB bus. To use the display, turn the OLED display power switch on. - Page 4 THE GPS RECEIVER SECTION The receiver module is mounted on a daughter board which plugs into headers on the main development board. This daughter board has an SMA antenna connector to allow the attachment of many different styles of GPS antennas. Figure 3: The Development Board GPS Receiver Section On the bottom of the main board is a CR2032 coin cell battery that provides power to the RTC and SRAM when the receiver is powered down.

THE DISPLAY SECTION The SG Series Master Development System features an OLED screen that displays the navigation information from the GPS module. This allows the development board to act as a stand-alone evaluation system without the need for any additional software. Figure 6: The Development Board Display Section The display is driven by an on-board microcontroller located under the display. -
