Product Overview
Achieve robust, centimeter-level RTK positioning in challenging RF environments with the SparkPNT LG290P GNSS Flex Module. This advanced module integrates the powerful Quectel LG290P receiver, featuring advanced anti-jamming technology ideal for navigation in urban canyons, industrial sites, or any location where signal integrity is critical.
As part of the SparkPNT Flex ecosystem, this module is designed to be easily swappable for repairs or future upgrades. It connects to your carrier board via standardized 2x10-pin headers, breaking out its triple UARTs, I²C* interface, and key timing and event signals.
Robust Quad-Band RTK
At 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

,L5
, andL6
/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 and a GNSS Flex carrier board (available in pHAT and Breakout options). Users should have two 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 on a GNSS Flex pHAT or Breakout carrier board can be utilized. Users can simply jumper the U.FL connectors between the SparkPNT GNSS Flex Module and the carrier board with a short U.FL cable.
*: 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.
