+  Configuring the GNSS to automatically send position reports over Serial
+  By: Nathan Seidle, Adapted from Example11 by Felix Jirka
+  SparkFun Electronics
+  Date: July 2nd, 2019
+  License: MIT. See license file for more information but you can
+  basically do whatever you want with this code.
+
+  This example shows how to configure the U-Blox GNSS the send navigation reports automatically
+  and retrieving the latest one via getPVT. This eliminates the blocking in getPVT while the GNSS
+  produces a fresh navigation solution at the expense of returning a slighly old solution.
+
+  This can be used over serial or over I2C, this example shows the Serial use. With serial the GNSS
+  simply outputs the UBX_NAV_PVT packet. With I2C it queues it into its internal I2C buffer (4KB in
+  size?) where it can be retrieved in the next I2C poll.
+
+  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!
+
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!

+
+  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
