LR9130(SiRF STAR 4E/Flash)

LR9130 is a SiRFstarIV solution(Flash Type), which is the same form factor and pin to pin compatible with LR9548SX. With flexible interface options, including UART, I2C, and SPI, the LR9130 can meet different needs in terms of design perspective. The LR9130 can be used in AVL, Notebook, and stationary devices.

The Leadtek LR9130 GPS module is a high sensitivity, low power, Surface Mount Device (SMD). 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™ single chipset, SiRF's newest chipset technology.
