In addition, the module can also give accurate and useful GNSS data in areas where satellite connections are
difficult to maintain: areas like the dense urban environments of major cities, long tunnels, parking garages, any
large UFO's that may descend from the sky, etc.

Hardware Overview
Power
Power for this board is 3.3V and we have provided multiple power options. This first and most obvious is the USB-
C connector. Secondly, are the Qwiic Connectors on the top and bottom of the board. Thirdly, there is a 5V pin
on the PTH header along the side of the board that is regulated down to 3.3V. Make sure that power your provide
to this pin does not exceed 6 volts. Finally, just below the 5V pin is a 3.3V pin that should only be provided a clean
3.3V power signal.
