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. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
