1 Introduction
1.1 Purpose
The GPS Evaluation Kit EVA2100-A allows an easy evaluation of Maestro’s
SiRFstarIV GPS receiver module A2100-A and A2100-B by offering quick access to
the serial ports and the most important I/O lines of the module.
The EVA2100-A serves three major purposes:
• As a demonstration package of the module’s capabilities
Powering the A2100-A GPS receiver module via the USB connector and
connecting the GPS antenna with sufficient view to the sky will result in an NMEA
output with position information.
• As an example how to integrate the module into a system
The schematic in chapter “10 Board Schematics” is a basic example of how to
integrate the GPS module into an application or system.
• To support an easy temporary design in
The signals provided on the Evaluation Kit allow direct integration into a
surrounding system making it an ideal development tool.
The EVA2100-A can especially demonstrate that an active or passive GPS antenna
connected to the Antenna Input will result in outstanding GPS performance. The user
can test with these two antenna types in order to evaluate the best solution for his
application.
