Sparkfun SparkPNT GNSS Flex Module - LG290P & IM19 IMU

Experience top-tier GNSS precision with the SparkPNT LG290P & IM19 GNSS Flex Module. This compact module combines the reliable LG290P RTK receiver with the IM19 IMU to deliver centimeter-level accuracy, tilt compensation, and robust anti-jamming capabilities. Easily upgradeable, it connects seamlessly to your GNSS Flex pHAT carrier board through standard 2x10-pin headers, offering interfaces like USB, dual UARTs, and I²C for effortless integration with Raspberry Pi or similar SBCs.

Perfect for demanding environments, this module excels in urban canyons or dense forests by utilizing the Quectel LG290P's multi-constellation and quad-band RTK capabilities. It processes signals from L1, L2, L5, and L6/E6 bands, ensuring rapid convergence and steadfast performance. Whether you're using standard RTK corrections, SBAS augmentation, or multiple PPP services, this module supports it all, including BDS PPP-B2b, QZSS CLAS, and Galileo HAS.

Benefit from advanced anti-jamming technology with a built-in NIC unit that detects and mitigates interference, safeguarding signal integrity even in complex electromagnetic environments. Embedded algorithms maintain reliable positioning, making it ideal for areas with poor satellite visibility.

Enhance your navigation with the intelligent pairing of the LG290P and the IM19 IMU. This duo offers high-precision attitude measurements through sensor fusion, enabling tilt-compensated surveying and stable navigation during GNSS signal interruptions. With survey-grade accuracy, roll and pitch measurements are precise to within 0.05 degrees, allowing for revolutionary field data collection without the need for perfectly vertical survey poles.

For seamless integration, the module's navigation data is automatically fed to the IMU, which outputs proprietary NMEA messages with fully compensated position and attitude data. This setup is easily adjustable via onboard jumpers to meet specific project requirements. An external antenna is necessary, with connection options available through a U.FL connector or a sturdier SMA connector on a GNSS Flex pHAT carrier board.
