+  Configure the NEO-M8P-2 as a "moving base"

+
+  This example configures the NEO-M8P-2 as a moving base.
+  It will output RTCM3 1077, 1087, 1230 and 4072.0 messages on UART1.
+  Connect UART1 TX to UART1 RX on a NEO-M8P rover. Also connect GND to GND.
+  The next example shows how to display the relative position of the rover.
+ 
+  Feel like supporting open source hardware?
+  Buy a board from SparkFun!
+  NEO-M8P RTK: https://www.sparkfun.com/products/15005
+
+  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)
+  Connect UART1 TX to UART1 RX on a NEO-M8P rover. Also connect GND to GND.
+  Open the serial monitor at 115200 baud to see the output
