Description :

SparkFun NEO-M9N GPS Breakout is a high quality GPS board
Receives signals from GPS, GLONASS, Galileo, and BeiDou constellations with ~1.5 meter accuracy
Supports concurrent reception of four GNSS, maximizing position accuracy and decreasing lock time
Has onboard rechargeable battery for backup power and hot lock within seconds
u-blox receiver supports I2C, compatible with Qwiic system (no soldering required) and has 0.1″-spaced pins for breadboarding
Can detect jamming and spoofing events and reports them to the host
Equipped with SAW filter and LNA for normal operation under strong RF interferences
Configurable with u-center program: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc
Configurable with SparkFun Arduino Library
On-board rechargeable battery provides power to the RTC on the NEO-M9N, reducing time-to-first fix from cold start to hot start
Battery maintains RTC and GNSS orbit data without power for a significant amount of time
