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.
Note: We support two versions of the SparkFun u-blox GNSS library. Version 2 and Version 3. Version 3 uses the u-blox Configuration Interface (VALSET and VALGET) to configure the module, instead of the deprecated UBX-CFG messages. For modules like the F9 and M10, we recommend upgrading to Version 3. However, older modules like the M8 do not support the Configuration Interface. For those you will need to keep using Version 2 of the library. We will continue to support both.

The SparkFun u-blox Arduino library can be downloaded with the Arduino library manager by searching 'SparkFun u-blox GNSS v3' or you can grab the zip here from the GitHub repository to manually install. Once calibrated, you can take advantage of the examples for the ZED-F9R.

There are 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 ZED-F9R. 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.
