SparkFun GNSS Flex pHAT - LG580P

Determine your Raspberry Pi's precise position and orientation with the SparkFun LG580P GNSS Flex pHAT. This compact development board is crafted for advanced navigation applications, merging a versatile pHAT carrier with the powerful LG580P module to deliver both centimeter-accurate RTK and real-time heading data. It's the perfect tool for intelligent robots, precision agriculture, and autonomous vehicle projects. The GNSS Flex pHAT serves as the bridge between your single-board computer (SBC) and the modular SparkPNT ecosystem, easily mounting via an extended 40-pin header and connecting to the included GNSS module with standardized 2x10-pin headers. The kit includes all necessary standoffs, screws, and an extended header for a tidy, stable setup.

The LG580P GNSS Flex pHAT is compatible with a variety of single-board computers, including Raspberry Pi, NVIDIA Jetson Orin Nano, and Google Coral, thanks to its 40-pin header designed for direct connection. This flexibility ensures that you can integrate the board into numerous projects without compatibility concerns. The included mounting hardware guarantees a secure and clean installation, making it easy to set up and swap modules for future upgrades.

At the core of this pHAT is the LG580P, a high-performance receiver that offers a comprehensive navigation solution for dynamic applications. It provides centimeter-level position accuracy and high-precision orientation data, essential for autonomous navigation and control. Its ability to simultaneously receive signals from L1, L2, L5, and L6/E6 bands across major constellations (GPS, GLONASS, Galileo, BDS, QZSS, and NavIC) ensures fast convergence and reliable performance, even in challenging environments like urban canyons or dense forests.

Advanced anti-jamming algorithms detect and mitigate interference, ensuring dependable operation in complex electromagnetic settings. With an update rate of up to 20 Hz for both position and heading, the LG580P is ideal for high-speed robotics and vehicle control systems. It supports standard RTK/RTCM corrections, a wide range of SBAS augmentation systems, and PPP services, offering versatility for various applications.

To operate, external antennas are required, with options for connecting via two U.FL connectors on the GNSS Flex Module. For a more robust connection, an SMA connector is available on the SparkFun GNSS Flex pHAT, bridged to a U.FL connector. Simply jumper the U.FL connectors on both the SparkPNT GNSS Flex Module and SparkFun GNSS Flex pHAT with a short U.FL cable. A Raspberry Pi or similar single-board computer is necessary for use, utilizing the primary serial bus by default for communication with the GNSS receiver, though other interfaces are also available.
