The Leadtek LR9548SX GPS module is a high sensitivity, low power, Surface Mount Device (SMD). This 20-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 SiRFstarIII GSC3f/LPx chipset, SiRF’s newest chipset technology. The LR9548SX is also pin-to-pin compatible with the LR9805-III (LR9548) for easier and faster transition.
