SparkFun GNSS Flex pHAT - mosaic-X5 & IM19 IMU

Elevate your Raspberry Pi projects with the SparkFun GNSS Flex pHAT, featuring the state-of-the-art mosaic-X5 RTK receiver and the precision IM19 IMU. This advanced GNSS board is designed for high-performance positioning, combining the Flex pHAT carrier with industrial-grade components to deliver millimeter-level accuracy. Ideal for professional surveying, industrial robotics, and critical autonomous systems, it provides seamless integration with single-board computers like Raspberry Pi, NVIDIA Jetson Orin Nano, and Google Coral through a 40-pin header. Key features include native USB-C access, a microSD card slot for data logging, and included mounting hardware for a stable setup.

Perfect for applications requiring precise positioning, this pHAT is an excellent choice for surveyors and engineers. The Septentrio mosaic-X5 receiver provides 6mm horizontal and 1cm vertical accuracy with RTK, while the IM19 IMU ensures high-precision attitude measurements. The combination allows for tilt-compensated surveying and reliable navigation even during brief GNSS outages, making it invaluable in urban or obstructed environments.

With the ability to track signals from all major constellations, including GPS, GLONASS, Galileo, BeiDou, and NavIC, the board ensures maximum satellite availability and fast, reliable fixes. Additionally, the AIM+ technology offers robust anti-jamming and anti-spoofing capabilities, maintaining signal integrity in noisy RF environments.

The user experience is further enhanced by the browser-based interface, allowing intuitive setup and monitoring via the USB connection. For advanced users, a Command-Line Interface (CLI) is available for deep configuration and control. The Flex pHAT is pre-configured for seamless integration with the IM19 IMU, providing a continuous navigation solution through sensor fusion, even during GNSS signal loss.

To optimize performance, an external GNSS antenna is required, with options for U.FL and SMA connections. The pHAT is designed to work with Raspberry Pi's primary serial bus but offers flexibility with other interfaces. This comprehensive solution is perfect for those seeking unparalleled positioning performance in their projects.
