Updated U$7 updated u$7 on brd and sch file to include value and part number

Schematic cleanup placed decoupling caps where they are located on the board. Placed items in groups and did my best to place nets near their origins. Also generally group items where they are located on the board.

added breakout mount holes added 2.8mm mounting holes with mouse bites for easy removal.

Schematic cleanup first pass at making the schematic more readable. Moved components to be more in line with the board layout.

Fixed airwire issue Fixed an issue with the v2 board that resulted from upgrading eagle to v9. It caused lots of very short airwires.

Added gps backup cap added gps backup capacitor. Corrected serial voltage divider resistor values. Removed ground vias below gps module.

fixed 3v reg the 3v reg wiring was corrected and output cap moved closer to the regulator.

added buck regulator swapped the linear regulator for a buck converter.

updated rf paths seperated RF GND from GND and coupled via an inductor. Implemented path cleanups. Made all RF impedence matched.

removed ldo and level shifter replaced the 3v ldo with a switching regulator, replaced level shifter with resistor dividers.
