SparkFun ZED-X20P GNSS Flex Modules

SparkFun ZED-X20P GNSS Flex Modules combine the all-band ZED-X20P RTK receiver with a high-precision IMU for centimeter-level accuracy. These flex modules are designed to be easily swappable and pin-compatible for future upgrades. The ZED-X20P flex modules connect to the GNSS Flex pHAT carrier board via standardized 2x10-pin headers that break out the module’s set of interfaces. The u-blox ZED-X20P concurrently processes signals from all major constellations (GPS, Galileo, and BeiDou) across all frequency bands. The GPS-29362 flex module comes with the ZED-X20P RTK receiver, and the GPS-28997 comes with both the ZED-X20P RTK receiver and the IM19 IMU. These GNSS flex modules are ideal for navigation and control applications.

The GPS-28997 module is designed for ZED-X20P and IM19 to work in symbiosis, and by default, the ZED-X20P's navigation data is automatically fed to the IMU. The IM19 then outputs proprietary NMEA messages containing the fully compensated position and attitude (roll, pitch, and yaw).
