SparkFun GNSS Flex pHAT - LG580P

Determine your Raspberry Pi's precise position and orientation with the SparkFun LG580P GNSS Flex pHAT. This all-in-one development board is engineered for advanced navigation applications combining our versatile pHAT carrier with the powerful LG580P module to deliver both centimeter-accurate RTK and real-time heading data. It's the ideal solution for intelligent robots precision agriculture and autonomous vehicle projects.The GNSS Flex pHAT acts as the bridge between your Raspberry Pi and the modular SparkPNT ecosystem. It mounts securely via an extended 40-pin header and connects to the included GNSS module using standardized 2x10-pin headers making it simple to swap modules for future upgrades. This kit includes all the necessary standoffs screws and an extended header for a clean stable setup.Raspberry Pi Connectivity: Standard 40-pin GPIO header for a direct secure connection.Mounting Hardware Included: Comes with the necessary standoffs screws and an extended header for a clean stable setup.Precision RTK & HeadingAt the heart of this pHAT is the LG580P a high-performance receiver that provides a complete navigation solution for dynamic applications.RTK + Heading: Delivers not only centimeter-level position accuracy but also high-precision attitude (orientation) data crucial for autonomous navigation and control.Quad-Band & Multi-Constellation: Simultaneously receives signals from the L1  L2  L5 and L6/E6 bands across all major constellations (GPS GLONASS Galileo BDS QZSS and NavIC) for fast convergence and performance even in challenging scenarios like urban canyons or deep tree cover.Advanced Anti-Jamming: Built-in algorithms detect and mitigate interference ensuring reliable operation in complex electromagnetic environments.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. Its versatility is further enhanced by broad support for standard RTK/RTCM corrections a wide range of SBAS augmentation systems (WAAS EGNOS BDSBAS MSAS GAGAN KASS ASECNA SouthPAN and SDCM) and PPP services* (BDS PPP-B2b QZSS CLAS MADOCA-PPP and Galileo HAS*).This product requires external antennas for operation. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.The GNSS Flex Module has two U.FL connectors for an external antenna.For a sturdier connection an SMA connector is available on the SparkFun GNSS Flex pHAT that is bridged to a U.FL connector. Users simply need to jumper the U.FL connectors on both the SparkPNT GNSS Flex Module and SparkFun GNSS Flex pHAT with a short U.FL cable.This pHAT also requires a Raspberry Pi (or similar single-board computer). Users can find Raspberry Pi and NVIDIA single-board computers in our catalog. By default we use the Raspberry Pi's primary serial bus (i.e. TX: GPIO14/Pin 8; RX: GPIO15/Pin 9) to communicate with the GNSS receiver. However users can also utilize any of the other interfaces.*According to Quectel support for the I²C interface is still under development and will be made available through a future firmware update. Additionally the corrections for some of the PPP services (like HAS E6) have not been implemented yet.
