Basic RX-TX Test

The first, and simplest test, is just to echo data back and forth using the Feather's USB connection to read the GPS

data out. The nice thing about this demo is no library is required.

Upload the following to your Feather, it will work with the Feather 32u4, M0, M4, WICED, etc. Anything that does not

have the RX/TX pins used to communicate.

This doesn't work with the ESP8266, ATmega328P or nRF52832 Feather! It will work on the nRF52840,

m32u4, M0, M4, Teensy, ESP32 and others
