SparkFun GPS Dead Reckoning NEO-M8U Hookup Guide
SparkFun u-blox Library
All of our u-blox based GPS boards share the same library: this board, their predeccesors and the higher precision u-blox cousins. The SparkFun U-blox Arduino library can be downloaded with the Arduino library manager by searching 'SparkFun u-blox GNSS' or you can grab the zip here from the GitHub repository to manually install.
There are 13 example sketches provided to get you up and receiving messages from space. The examples listed below highlight the additional capabilities of the SparkFun Dead Reckoning NEO-M8U. For the scope of this tutorial, we will not focus on the basic GPS polling sketches as shown in the other u-blox hookup guides.
