+  Set Dynamic Model

+  basically do whatever you want with this code.
+
+  This example shows how to change the Ublox module's dynamic platform model and then
+  query its lat/long/altitude. We also turn off the NMEA output on the I2C port.
+  This decreases the amount of I2C traffic dramatically.
+
+  Possible values for the dynamic model are: PORTABLE, STATIONARY, PEDESTRIAN, AUTOMOTIVE,
+  SEA, AIRBORNE1g, AIRBORNE2g, AIRBORNE4g, WRIST, BIKE
+
+  Note: Long/lat are large numbers because they are * 10^7. To convert lat/long
+  to something google maps understands simply divide the numbers by 10,000,000. We
+  do this so that we don't have to use floating point numbers.
+
+  Leave NMEA parsing behind. Now you can simply ask the module for the datums you want!
+
+  Feel like supporting open source hardware?

+
+  Hardware Connections:
+  Plug a Qwiic cable into the GPS 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
