Version 1.3.1

Pin Explanation

RF: Connects to a patch, or an 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 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 start 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 5.0 V.

(NOTE:This pin must be kept “HIGH” for operation. From Vcc connect a 470 Ohm resistor in series with a

3.2v Zener diode to Ground. Then, connect the VBAT input to Zener’s cathode to pull the input “HIGH”.)

GPI01: User can use this I/O pin for special functions (for example, an on/off indicator LED).

TX: This is the main transmit channel for outputting navigation and measurement data to user’s

navigation software or user-written software.

RX: This is the main channel for receiving software commands to the engine board from SiRF demo

software or from user-written software.

GND: GND provides the ground for the engine board. Be sure to connect all grounds.
