SparkFun GNSS Flex pHAT - LG290P

Achieve robust centimeter-level RTK positioning in challenging RF environments with the SparkFun LG290P GNSS Flex pHAT. This all-in-one development board combines our versatile pHAT carrier with the powerful Quectel LG290P module featuring advanced anti-jamming technology ideal for navigation in urban canyons industrial sites or any location where signal integrity is critical.The GNSS Flex pHAT acts as the bridge between your single-board computer (SBC) 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.Multiple SBC Compatibility: The 40-pin header is designed for a direct connection to a Raspberry Pi NVIDIA Jetson Orin Nano Google Coral or other compatible single-board computers.USB-C Port: Provides an alternative data interface to the GNSS module.Mounting Hardware Included: Comes with the necessary standoffs screws and an extended header for a clean stable setup.Robust Quad-Band RTKAt the heart of this pHAT is the Quectel LG290P a high-precision receiver engineered for fast convergence and reliable performance when it matters most.Advanced Anti-Jamming: A built-in NIC anti-jamming unit provides professional-grade interference detection and mitigation ensuring signal integrity in complex electromagnetic environments.Quad-Band & Multi-Constellation: Simultaneously receives signals from the L1  L2  L5 and L6/E6 bands across all major constellations for robust performance even in challenging scenarios like urban canyons or deep tree cover.Centimeter-Level RTK: Delivers high-precision Real-Time Kinematic positioning for applications requiring exacting accuracy.Broad Correction Support: Supports standard RTK/RTCM corrections a wide range of SBAS augmentation systems and PPP services*.This product requires an external antenna. Users have a few options for connecting an external GNSS antenna to their GNSS receiver.The GNSS Flex module has a U.FL connector 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 of the SparkPNT GNSS Flex module. However users can also utilize any of the other interfaces.*: Feature is still under development. Currently only the UART interfaces are supported by the LG290P module. Additionally corrections for some of the PPP services may not have been implemented yet.
