Version 1.3.1

Pin Explanation

VCC: (DC power input) This is the main DC supply for a 3.8V ~ 6.5V power module board.

VBAT: This is the battery backup input that powers the SRAM and RTC when main power is removed.

Typical current draw is 10uA. 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. To maximize battery lifetime, the battery voltage should be between 2.5v and

3.6v.

PBRES: (Push Button Reset) This pin provides an active-low reset input to the engine board. It causes

the engine board to reset and start searching for satellites.

SELECT: Do not connect (do not use)

TX: This is the main transmit 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. (NOTE:When not in use 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 Rx input to Zener’s cathode to pull the input “HIGH”.)

TIME MARK (1PPS): This pin provides one pulse-per-second output from the engine board that is

synchronized to GPS time

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

Mounting

Recommended mounting methods:

a. Use industrial grade double-sided foam tape. Place it on the bottom side of the engine board.

b. A recessed cavity in your housing design with a foam pad to eliminate shifting or movement.

c. Use provided mounting holes on the GPS engine board PCB.
