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.
Housed in a compact reflow-compatible SMD package, the receiver
requires no programming or additional RF components (except an antenna)
to form a complete GPS solution. This makes the FM Series easy to
integrate, even by engineers without previous RF or GPS experience.
