If you have not already, select your Board (in this case the SparkFun ESP32 MicroMod), and associated COM
port. Upload the code to the board and and set the Arduino Serial Monitor to 115200 baud. Give the ZED-F9P a
few minutes to get a satellite lock. The GPS coordinates and the accuracy will be output in the Serial Monitor.

Now that you got it up and running, check out the other examples located in the ZED-F9P folder!
Of course, to get the most out of the ZED-F9P, you will need an RTCM correction source. Depending on your
setup, you will probably need a second ZED-F9P for a correction source. The following project tutorials allow you
to set up the ZED-F9P as a reference station or rover.
