The Sparkfun SparkPNT GNSS Flex Module - LG290P & IM19 IMU is a sophisticated, swappable module designed for high-precision positioning applications. It features the Quectel LG290P receiver, which provides advanced anti-jamming capabilities and integrates with the IM19 Inertial Measurement Unit for tilt-compensated positioning. This module is engineered to deliver centimeter-level accuracy, ensuring precise and reliable data for various navigation and tracking needs.
The module is designed for easy integration and future upgrades, connecting seamlessly to a GNSS Flex pHAT carrier board through standardized 2x10-pin headers. It supports multiple GNSS constellations, including GPS, GLONASS, Galileo, BDS, QZSS, and NavIC, and is compatible with several SBAS systems such as WAAS, SDCM, EGNOS, BDSBAS, MSAS, and GAGAN. This broad compatibility ensures robust performance across different global regions.
The SparkPNT GNSS Flex Module operates on a supply voltage of 3.3V and features multiple interfaces, including UART and I2C, for versatile connectivity options. It is equipped with LED indicators for status monitoring and supports an external active GNSS antenna for enhanced signal reception. The module's dynamic performance is notable, with a maximum altitude capability of 10,000 meters and a velocity limit of 490 meters per second.
The IM19 IMU enhances the module's functionality by providing accurate inertial measurements, with an operating range that includes an accelerometer and gyroscope. This integration allows for precise roll, pitch, and heading data, making the module suitable for applications requiring detailed orientation information.
