The SparkFun XA1110 GPS Breakout is a small I2C-supported module built for easy hookup, thanks to our Qwiic Connect System. Equipped with the XA1110 GPS module from GTOP, this board utilizes the MediaTek MT3333 chipset, loaded with specialized SparkFun firmware that enables both I2C and serial ports simultaneously. Using I2C means you won’t have to tie up your serial port with GPS, leaving it open to other possibilities.
This GPS Breakout supports up to 210 PRN channels with 99 search channels and 33 simultaneous tracking channels. With support of GPS, GLONASS, QZSS, SBAS and more, the onboard XA1110 can provide even more accurate positioning in multiple locations. Additionally, the XA1110 GPS Breakout is configured with an onboard RTC battery that enables a warm-start functionality, giving the X1 just five seconds to first fix, as well as a U.FL connector that provides you the option to hook up an external antenna via a U.FL cable.
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.
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GLONASS
- Russia’s satellite navigation system. A receiver that can also use GLONASS has more satellites to choose from, which can improve positioning reliability when the sky view is partly blocked.
- GPS
- The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- QZSS
- Japan’s regional satellite navigation system designed to improve coverage around Japan and the Asia-Pacific region. QZSS support can improve satellite availability in supported regions when used alongside GPS.
- RTC
- A Real-Time Clock keeps track of time even when the main processor is asleep or powered down, usually with a small backup battery. It matters for data logging and tracking projects that need accurate timestamps.
- SBAS
- Satellite-Based Augmentation System, a set of regional services that broadcast correction information for GNSS receivers. SBAS can improve ordinary GPS-style positioning, although it is not the same as centimetre-level RTK correction.
- u.FL
- u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.
