Added changes to SD card, boot select, and GND connect.

Rev 3 changes

Schematic was wrong for sd card. Fixed the symbol and footprint for sd card. Motor driver layout needs serious work. Ignore second pcb file. That was just an experiment to see if I could improve the layout.

Fixed Reference Designators

Most of the board is done. Just need to change the layer of the signal lines.

Preliminary Layout has begun.

Organized footprints for PCB Layout

Board updates

This is the first test of creating a branch and pushing to that branch.

New schematics. Go to town on this.
