SparkFun RTK Express Hookup Guide

This Arduino tutorial will teach you how to pinpoint and display your GPS coordinates with a press of a button using hardware from our Qwiic Connect System (I2C).

Let's ramp up our GPS tracking skills with KML files and Google Earth. We'll make a tracker that logs location and allows us to visualize our steps with Google Earth.

The u-blox NEO-M8U is a powerful GPS units that takes advantage of untethered dead reckoning (UDR) technology for navigation. The module provides continuous positioning for vehicles in urban environments and during complete signal loss (e.g. short tunnels and parking garages). We will quickly get you set up using the Qwiic ecosystem and Arduino so that you can start reading the output!

Setup the RTK Facet in minutes to begin gathering millimeter level geospatial coordinates.

Hookup guide for the ESP32 Thing Plus (Micro-B) using the ESP32 WROOM's WiFi/Bluetooth system-on-chip in Arduino.

How to install CH340 drivers (if you need them) on Windows, Mac OS X, and Linux.

Getting GNSS RTCM correction data from a base to a rover is easy with a serial telemetry radio! We'll show you how to get your high precision RTK GNSS system setup and running.

Learn how to affix a GNSS antenna, use PPP to get its ECEF coordinates and then broadcast your own RTCM data over the internet and cellular using NTRIP to increase rover reception to 10km!
