Finished all comms bus assignments, ready for tracing

Schematic is almost finished. Going to start the layout anyway since we need to have this done.

Due to stock issues, adjusted IMUs and add multiplexer to handle multiple I2C devices; and more...

Started wiring the interfaces together. Follow my example for wiring the circuitry to the MCU. Once this is done I can begin the layout.

Finished BOM

Stash of changes before pulling Richard's changes

Worked on the BOM some more. Still need to add the SD card, crystal oscillators, and ferrite bead.

Added some more parts to the BOM. Almost done, but have to get going.

Added a buffer for reading digital signals. Will add a pinheader tomorrow. Also added LEDs to indicate power. Still need to finish the BOM and then connect all devices to the MCU.

Rearraged come of the circuits and added new circuitry for the stepper motor driver.
