SparkFun GNSS Flex pHAT - LG290P & IM19 IMU

The SparkFun GNSS Flex pHAT - LG290P & IM19 IMU combines Quectel's cutting-edge GNSS technology with the versatility of the SparkPNT ecosystem. This compact module features the LG290P RTK receiver and IM19 IMU, delivering centimeter-level accuracy, full tilt compensation, and advanced anti-jamming capabilities. It connects effortlessly to single-board computers (SBCs) like Raspberry Pi, NVIDIA Jetson Orin Nano, and Google Coral through a 40-pin header. The package includes all necessary mounting hardware for a stable setup.

Perfect for precision applications, the GNSS Flex pHAT excels in a variety of scenarios. Whether you're conducting a topographical survey or navigating complex urban environments, it provides reliable performance. The multi-constellation receiver supports L1, L2, L5, and L6/E6 bands, allowing for rapid convergence and dependable positioning even in dense urban canyons or under heavy tree cover.

The module's RTK and PPP readiness ensures it can handle standard corrections and augmentations, providing flexibility for various professional applications. Advanced anti-jamming features maintain signal integrity in challenging electromagnetic conditions, making it a robust choice for high-demand environments.

Integrating the IM19 IMU with the LG290P, the module offers intelligent tilt and dead reckoning capabilities. This allows for tilt-compensated surveying and seamless navigation through brief GNSS outages. With survey-grade accuracy, it measures roll and pitch to within 0.05 degrees, revolutionizing field data collection by eliminating the need for perfectly vertical survey poles.

The GNSS Flex pHAT is designed for seamless integration and connectivity. The LG290P's navigation data is automatically fed to the IMU, which outputs compensated position and attitude data. Users can easily reconfigure this setup via onboard jumpers to suit specific project needs. The module requires an external antenna and a GNSS Flex carrier board, with options for U.FL or SMA connections for enhanced flexibility.

Compatible with a range of SBCs, the GNSS Flex pHAT uses the Raspberry Pi's primary serial bus for communication with the GNSS receiver and an alternate serial bus for the IMU. Future firmware updates will expand interface support, ensuring the module remains a versatile tool for cutting-edge applications.
