NEO-M9N GPS 모듈 -UFL 커넥터
(SparkFun GPS Breakout - NEO-M9N, U.FL (Qwiic))
개요
- 본 제품은 외장 안테나 연결을 위한 UFL 커넥터를 보드상에 장착하고 있는 NEO-M9N GPS 모듈입니다.
- NEO-M9N은 92채널 u-blox M9 엔진 GNSS 리시버로 GPS, GLONASS, Galileo, BeiDou 위성신호를 수신할 수 있습니다.
- 4개의 GNSS 신호를 동시에 수신하는 것을 지원하여 위치정보의 정확도를 높일수 있으며, 보드에 장착된 배터리를 이용하여 GPS가 수초이내에 hot start 될수 있게 하여 줍니다.
- I2C 인터페이스를 지원합니다.

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 into 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.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.
