SparkFun NEO-M9N GPS Breakout ,Chip Antenna (Qwiic) U-BLOX 高精度GPS 支援 I2C 通訊

SparkFun NEO-M9N GPS Breakout 帶有機載芯片天線的SparkFun NEO-M9N GPS Breakout是一款高質量的GPS板，同時具有令人印象深刻的配置選項。NEO-M9N模塊是92通道u-blox M9引擎GNSS接收器，這意味著它可以從GPS，GLONASS，伽利略和北斗星座接收信號，精確度約為1.5米。該突破口支持同時接收四個GNSS，從而在挑戰性條件下最大程度地提高了定位精度，從而提高了精度並減少了鎖定時間，並且由於板載可充電電池，您將擁有備用電源，使GPS能夠在幾秒鐘內獲得熱鎖定！此外，此u-blox接收器支持I ²C（u-blox稱為顯示數據通道）非常適合Qwiic兼容性，因此我們不必耗盡寶貴的UART端口。利用我們方便的Qwiic系統，無需焊接即可將其連接到系統的其餘部分。但是，如果您更喜歡使用麵包板，我們仍然會斷開0.1英寸間距的插針。

NEO-M9N 模塊可以檢測干擾和欺騙事件，並可以將其報告給主機，以便系統可以對此類事件做出反應。NEO-M9N模塊中集成了SAW（表面聲波）濾波器和RF路徑中的LNA（低噪聲放大器），即使在強烈的RF干擾下也可以正常工作。

基於U-blox的GPS產品可以使用流行但密集的Windows程序（稱為u-center）進行配置。可以在NEO-M9N上配置很多不同的功能：波特率，更新率，地理圍欄，欺騙檢測，外部中斷，SBAS / D-GPS等。所有這些都可以在SparkFun Arduino庫中完成！

英國威廉希爾 SparkFun NEO-M9N GPS Breakout 還配備了車載可充電電池，可為NEO-M9N上的RTC供電。這樣可以將首次修復時間從冷啟動（〜24s）減少到熱啟動（〜2s）。電池將保持RTC和GNSS軌道數據，而無需長時間連接電源。

SparkFun GPS Breakout – NEO-M9N, Chip Antenna (Qwiic)

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 we don’t have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1″-spaced pins in case you prefer to use a breadboard.

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.
