Description
The FM Series GPS receiver module is a self-contained high-performance
Global Positioning System receiver. Based on the MediaTek MT3339
chipset, it can simultaneously acquire on 66 channels and track on up
to 22 channels. This gives the module fast lock times and high position
accuracy even at low signal levels.
The module’s exceptional sensitivity gives it superior performance, even in
dense foliage and urban canyons. Its very low power consumption helps
maximize runtimes in battery powered applications. The module outputs
standard NMEA data messages through a UART interface. These features
make it easy to integrate, even by engineers without previous RF or GPS
experience. The Linx FM Series GPS modules offer a simple, efficient and
cost-effective method of adding GPS capabilities to any product.
The evaluation module contains the surface mount FM Series GPS module,
SMA connector and a ferrite bead (used to supply power to an external
active antenna, such as the Linx SH Series active GPS antenna) on a single
board with through-hole headers. This small board makes prototyping with
the FM Series module very easy.
