Leadtek LR 9123 is a high performance, low power consumption, small size,
easily integrated GPS module board designed for a broad spectrum of OEM
system applications. This product is based on SiRFstarIII/LPx single chipset
solution. Leadtek LR9123 module board is very fit to the customers who devote themselves
to AVL system integration and location-based service.
The LR9123 design utilizes the latest surface mount technology and high level
circuit integration to achieve superior performance while minimizing space and
power requirements. This hardware capability combined with software intelligence
makes the board easy to be integrated and used in all kinds of navigation
applications or products. The application system may communicate with the module
board set via two RS232 compatible bi-directional communication channels with
CMOS/TTL voltage level.
