SparkFun NEO-M9N GPS Breakout with SMA and Qwiic

The SparkFun NEO-M9N GPS Breakout is a high-accuracy GNSS receiver board with an SMA antenna connector and Qwiic I2C interface, built around the u-blox NEO-M9N module.

Key features

• Tracks GPS, GLONASS, Galileo and BeiDou constellations concurrently across a 92-channel receiver for around 1.5m horizontal accuracy.
• Qwiic connector allows a solder-free I2C link to a host board, while breadboard-friendly 0.1in pins remain broken out.
• An onboard rechargeable battery backs up the module's clock, giving hot starts in about 2 seconds versus a 24-second cold start.
• Built-in SAW filter and LNA reject RF interference, and the module can report jamming or spoofing events to the host.
• Supports NMEA, UBX and RTCM protocols over UART or I2C, covering most flight-controller and telemetry integrations.
