SparkFun NEO-M9N GPS Breakout

SparkFun NEO-M9N GPS Breakout is a global positioning satellite board with versatile configuration options. NEO-M9N GPS Breakout includes an integrated U.FL connector to boost reception. The 92-channel u-blox M9 engine Global Navigation Satellite System (GNSS) receiver can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with 1.5-meter accuracy. NEO-M9N GPS Breakout utilizes the concurrent reception of four GNSS to maximize position accuracy in challenging conditions. This enables increased precision and decreased lock time. NEO-M9N GPS Breakout is also equipped with an onboard rechargeable battery that provides power to the RTC on the NEO-M9N. The u-blox receiver supports I2C, making it ideal for Qwiic compatibility. The module detects jamming and spoofing events and can report them to the host, so the system can react to such events.
