SE867-AGPS evaluation kit

11.1.

Short description

In order to give the customer the possibility to evaluate the performances of Telit
SE867-AGPS module in all the available configurations, an evaluation kit has been
developed.

The evaluation kit consists in a single board with:



SE867-AGPS module



Mini USB connector for power supply and data communication with a PC



FTDI chip for USB to UART conversion



SMA RF connector for optional external active antenna or instrument connection



On board passive a LNA (currently non available, future use only)



DIP switches for configuration options selection

Thanks to the onboard FTDI chip the USB connection is seen as a Virtual COM Port by
the PC after the installation of the FTDI VCP drivers (available for free at

http://www.ftdichip.com/Drivers/VCP.htm

).

All the customer needs to work with this evaluation board is a PC to connect with the
evaluation kit and software to perform NMEA data flow reading and position fixing (e.g.
Visual GPS, available for free in Internet).
