SparkFun ZED-X20P (Qwiic) Allband GNSS RTK Breakout Board

SparkFun ZED-X20P (Qwiic) Allband GNSS RTK Breakout Board features the X20 GNSS engine from u-blox, which is a successor to the popular F9 engine. This breakout board includes diverse interfaces, including USB, UART, SPI, and I2C. The ZED-X20P (Qwiic) breakout board comes with the dimensions of 1.70" x 1.70" (43.2mm x 43.2mm) with 4-40 screw compatible 4 mounting holes. The ZED-X20P module is an all-band, high-precision GNSS receiver that processes signals across all GNSS frequency bands from the GPS, Galileo, BeiDou, QZSS, and NavIC constellations. The ZED-X20P (Qwiic) breakout board is ideal for navigation systems, robotics, Unmanned Autonomous Vehicles (UAVs), guidance systems, and auto-steering.
