DE0-Nano schematics and datasheets, LY3200 gyro, moved connector
datasheet
Added datasheets and folders for reference mouse v2
Rearranged folder structure so that projects are top-level
Removed old directory structure
Added datasheets
Moved a datasheet.
Began development on FPGA mouse board internals.

This seems difficult.
Added all FPGA parts and updated excel sheet of pinout.
Commiting with corrected file paths
Schematic things have been updated
A lot of kicad.... A LOT.
Did a 3D drivetrain on refmouse 2
Made changes to board 20% done still. :/
Changed DRV8837, Almost completed main board.
ERC almost successful.
Changed directory structure, where did the fpga board go?
re-added the fpga parts... I wonder where everything went o.0
Removed that pesky noname.pro file.
Finalized connector structure.
Okay, now the connector is finalized.
Git says some inventor files changed, so here
