SparkFun NEO-M9N GPS - Qwiic Chip Antenna

The SparkFun NEO-M9N GPS Breakout with on-board chip antenna is a high quality, GPS board with equally impressive configuration options. The NEO-M9N module is a 92-channel u-blox M9 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations witn ~1.5 meter accuracy. This breakout supports concurrent reception of four GNSS maximizes position accuracy in challenging conditions increasing precision and decreases lock time and thanks to the onboard rechargeable battery, you'll have backup power enabling the GPS to get a hot lock within seconds. Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so you don't have to use up your UART ports. Utilizing SparkFuns' handy Qwiic system, no soldering is required to connect it to the rest of your system.

The NEO-M9N module detects jamming and spoofing events and can reports them to the host, so that the system can react to such events. A SAW (Surface Acoustic Wave) filter combined with an LNA (Low Noise Amplifier) in the RF path is integrated in the NEO-M9N module which allows normal operation even under strong RF interferences.

U-blox based GPS products are configurable using the popular, but dense, windows program called u-center. Plenty of different functions can be configured on the NEO-M9N: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library.

The SparkFun NEO-M9N GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M9N. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.
