Pin Assignment

Pin description

* RF:

Connect to Patch Antenna

Connect to External Active Antenna

* VIN (DC power input):

This is the main DC supply for a 3.3V +- 5% DC input power module board.

* BATTERY (Backup battery):

This is the battery backup input that powers the SRAM and RTC when main

power is removed. Typical current draw is 15uA. Without an external backup battery,

the module/engine board will execute a cold star after every turn on. To achieve the

faster start-up offered by a hot or warm start, a battery backup must be connected.

The battery voltage should be between 2.0v and 5.0v.

* GPIO13:

User can use this I/O pin for special function.

For example, on/off LED

* TX:

This is the main transmits channel for outputting navigation and measurement

data to user’s navigation software or user written software.

Output TTL level, 0V ~ 2.85V

* RX:

This is the main receive channel for receiving software commands to the engine

board from SiRFdemo software or from user written software.

* GND:

GND provides the ground for the engine board. Connect all grounds.
