SparkFun u-blox Arduino Library
Note: This example assumes you are using the latest version of the Arduino IDE on your desktop. If this is your first time using Arduino, please review our tutorial on installing the Arduino IDE. If you have not previously installed an Arduino library, please check out our installation guide.
All of our u-blox based GPS boards share the same library: these two boards, 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. We'll go over one of the examples in this tutorial.
Note: Example 2 uses the 'MicroNMEA' library by Steve Marple. Make sure to install the library as well by searching for it in the Arduino library manager. You could also grab the zip here from the GitHub repository to manually install.
