PINASSIGNMENT
PIN DESCRIPTIONS VCC: (DC power input): This is the main DC supply for a 4.5V ~ 6.5V power module board. 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 receive channel for receiving software commands to the engine board from SiRfdemo software or from user-written software. Normally this pin must be kept High and if you don’t use this pin please connect a resistor to 3.5V to pull it high. GND: GND provides the ground for the engine boards. Be sure to connect all grounds PPS: This pin provides a one pulse-per-second output from the engine board that is synchronized to the GPS time.

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.
