Definition of Pin assignment

VCC(+3.3V DC power Input)

This is the DC power supply input pin for GPS system. It provides voltage to module.

GND

GND provides the reference ground.

TXA

This is the main transmitting channel and is used to output navigation and measurement data to SiRFdemo or user written software

RXA

This is the main receiver channel and is used to receive software commands to the board from SIRFdemo software or from user written software.

VBATT (Backup battery )

When module is working, must to supply VCC pin(Pin1) and VBATT pin(Pin6) power at the same time.

This is the battery backup input that powers the SRAM and RTC when main power is removed. Typical current draw is 10uA.

The supply voltage should be between 2.5V and 3.6V.

GPIO Functions

Several I/Os are connected to the digital interface connector for custom applications.
