+  Read NMEA sentences over I2C using u-blox module SAM-M8Q, NEO-M8P, ZED-F9P, etc

+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example reads the NMEA setences from the u-blox module over I2c and outputs
+  them to the serial port
+  
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!
+  ZED-F9P RTK2: https://www.sparkfun.com/products/15136
+  NEO-M8P RTK: https://www.sparkfun.com/products/15005
+  SAM-M8Q: https://www.sparkfun.com/products/15106
+
+  Hardware Connections:
+  Plug a Qwiic cable into the GNSS and a BlackBoard
+  If you don't have a platform with a Qwiic connection use the SparkFun Qwiic Breadboard Jumper (https://www.sparkfun.com/products/14425)
+  Open the serial monitor at 115200 baud to see the output
