GPS modules are common these days but the Qwiic GPS is something extremely rare: this is a true I2C GPS+GLONASS module. The Qwiic GPS uses the brand new Titan X1 from GTOP. This is an ultra-compact module that uses the MediaTek MT3333 chipset that has been loaded with SparkFun specialized firmware that enables both the I2C port and serial at the same time. I2C means you can stop worrying about tying up your hardware serial port and start adding GPS to your project!

The Qwiic GPS has a variety of features that set it apart from the competition including an on-board RTC battery that will maintain warm-start functionality (5 seconds to first fix). A U.FL connector allows an external antenna with U.FL cable to be used for outdoor and automotive applications. Additionally we’ve written a library that makes reading and controlling the GPS over I2C a breeze. The example sketches show how to increase the update rate to 10 Hz, enable high balloon experiments, enable SBAS/DGPS, turn on/off sentences, and change the baud rate.

We are truly impressed with the staggeringly fast lock of this module with an impressive HDOP of less than 1.

We do not plan to regularly carry SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly located and produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees.

GPS模塊是常見的,但是Qwiic GPS是非常罕見的:這是一個真正的I 2 C GPS + GLONASS模塊。 Qwiic GPS使用GTOP的全新Titan X1。這是一個超緊湊型模塊,它使用已加載SparkFun專用固件的聯發科MT3333芯片組,同時支持I 2 C端口和串行連接。我2 C意味著你可以停止擔心綁定你的硬件串口,並開始添加GPS到你的項目!

Qwiic GPS具有各種功能,將其與競爭對手相比,包括可保持熱啟動功能的車載RTC電池(5秒鐘首次修復)。 U.FL連接器允許使用U.FL電纜外部天線用於室外和汽車應用。此外,我們編寫了一個庫,可以讓I 2 C輕鬆讀取和控制GPS。示例草圖顯示如何將更新速率提高到10 Hz,啟用高氣球實驗,啟用SBAS / DGPS,打開/關閉句子以及更改波特率。

令人印象深刻的是,該模塊具有驚人的快速鎖定,令人印象深刻的是HDOP低於1。

我們不打算定期攜帶SparkX產品,讓他們在熱的時候!
