The USB Section

The development board features a Linx QS Series USB module for

interface to a PC. This allows the board to be used with the supplied

development software or with custom software developed by the user.

Drivers for the USB module are included on the software CD in the kit

or may be downloaded from www.linxtechnologies.com. Additional

information on using the QS Series USB module can also be found on the

website.

The USB connection also allows the board to be powered by the USB

bus instead of batteries. This can be convenient during development to

eliminate the need for frequent battery replacement.

The Receiver Section

The receiver module is mounted on an evaluation board which plugs into

headers on the main development board. The evaluation board has an

SMA antenna connector to allow the attachment of many different styles of

GPS antennas, including the included SH Series active GPS antenna. Each

receiver module has its own evaluation board, but all of them are designed

to fit into the same socket on the main board.

On the bottom of the main board is a CR2032 coin cell battery that

provides power to the Real Time Clock (RTC) and SRAM when the receiver

is powered down. This allows the receiver to start up and obtain a position

fix faster. This cell provides about two years of operation.
