We've also written an extensive Arduino library for u-blox modules to make reading and controlling the GPS-RTK-SMA over our Qwiic Connect System easy. The GPS-RTK2 even has five communications ports which are all active simultaneously: USB-C (which enumerates as a COM port), UART1 (with 3.3V TTL), UART2 for RTCM reception (with 3.3V TTL), I2C (via the two Qwiic connectors or broken out pins), and SPI. The number of configuration options of the ZED-F9P is incredible! Geofencing, variable I2C address, variable update rates, even the high precision RTK solution can be increased to 20Hz. Based on your feedback, we switched out the u.FL connector and included an SMA connector in this version of the board. This module features a survey-in mode allowing the module to become a base station and produce RTCM 3.x correction data. This battery helps 'warm-start' the module decreasing the time-to-first-fix dramatically. We've included a rechargeable backup battery to keep the latest module configuration and satellite data available for up to two weeks. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. With this board, you will be able to know where your (or any object's) X, Y, and Z location is within roughly the width of your fingernail! The ZED-F9P is unique in that it is capable of both rover and base station operations. The ZED-F9P is a top-of-the-line module for high accuracy GNSS and GPS location solutions including RTK that is capable of 10mm, three-dimensional accuracy. This means the higher the accuracy the better! GPS Real Time Kinematics (RTK) has mastered dialing in the accuracy of their GPS modules to just millimeters, and that's why we had to put it on this board!īased on the SparkFun GPS-RTK2 designs, the SparkFun GPS-RTK-SMA raises the bar for high-precision GPS and is the latest in a line of powerful RTK boards featuring the ZED-F9P module from u-blox. With GPS you are able to know where you are, where you're going, and how to get there anywhere on Earth within 30 seconds.
