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.
