Leadtek LR9131 SiRF Star IV GPS Module GPS Engine Board GPS Receiver Module 15x14mm

Introduction
The LR9131 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that fully utilized SiRFstarIV upgrade features. This 48-channel global positioning system (GPS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarIV GSD4e chipset, SiRF’s newest chipset technology.
The Ct-G431 provides flexible Bus interfaces (UART and I2C by customer requirement).

The LR9131 is designed to allow quick and easy integration into GPS-related applications such as:
- PDA, Pocket PC, Tablet and other computing devices
- Fleet Management /Asset Tracking
- AVL and Location-Based Services
- Hand-Held Device for Personal Positioning and Navigation
- All applications of battery drive device that needs lower power consumption
