GPS MODULE EVALUATION BOARD
Jumper Settings
The Pin Headers provide access to the GPS modules pins.
Pin 1 of each of the pin headers connects through to the
GPS module as indicated in the table below. Pin 2 of each
pin header is connected to ground.
Please refer to the Data Interface section on page 4 of
datasheet DS031 for information on the functionality of
these pins.

Power Connections
Power can be supplied to the board at either 3.3Vdc or 4-
9Vdc via the 3V3 or JP1 pin headers respectively.
Data Connections
Data access is provided at either RS232 or TTL voltage
levels.
• The 9-way D-Type connector provides data transfer at
RS232 voltage levels. It may be connected directly to a
COM port of a PC.
• The COMMS pin header provides direct access to the
GPS module 3.3V data lines.
COMMS_1 = GPS Data Transmit
COMMS_2 = GPS Data Recieve
In this case the RS232 Driver chip can be disabled by
removing R3 and R9.
Status LEDs
LED1 (the green LED) illuminates to indicate that a valid almanac is available.
LED2 (the red LED) flashes to indicate that no GPS information is available.
LED2 remains off if GPS information is available.
PCB Dimensions: 85.5mm x 33.5mm
