SparkFun GPS Breakout - XA1110 (Qwiic)

The SparkFun XA1110 GPS Breakout is a compact, I²C-supported module, designed for seamless integration thanks to the Qwiic Connect System. This board is powered by the XA1110 GPS module from GTOP and uses the MediaTek MT3333 chipset, enhanced with SparkFun firmware. This firmware allows the simultaneous usage of both I²C and serial ports, freeing up your serial port for other applications.

The XA1110 GPS Breakout supports up to 210 PRN channels, 99 search channels, and 33 simultaneous tracking channels. It also supports GPS, GLONASS, QZSS, SBAS and more, making it possible to achieve highly accurate positioning in numerous locations. The XA1110 GPS Breakout comes with an onboard RTC battery that enables a warm-start functionality, allowing the X1 to first fix in just five seconds. Additionally, it features a U.FL connector, providing the option to connect an external antenna via a U.FL cable.

It's important to note that the I²C address of the XA1110 is 0x10 and is hardware defined. A multiplexer/Mux is required to communicate with multiple XA1110 sensors on a single bus. If you plan on using more than one XA1110 sensor, consider using a Qwiic Mux Breakout.

The SparkFun Qwiic Connect System simplifies the prototyping process, reducing errors. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, which not only minimizes the required PCB space but also ensures correct connections due to its polarized design.

Key features of the SparkFun XA1110 GPS Breakout include a 33 tracking/99 acquisition-channel GPS +GLONASS receiver, support for QZSS & SBAS (WAAS, EGNOS, MSAS, GAGAN), sensitivity of -165dBm, an update rate of up to 10Hz, a 12 multi-tone active interference canceler, two Qwiic connectors, a U.FL connector, and an onboard RTC battery.
