Board files have been successfully submitted to PCBWay for approval and fabrication. With the demo code working and the design off to manufacturing, I'm satisfied that I have done everything I can to meet the minimum requirements for contest qualification. Still, there are many things to do in preparation for the boards arriving:

• Clean up the Git repo and upload the design files there and here
• Order the parts (now that they're all available for purchase)
• Work on the docs
• Make a few "set-and-forget" example programs (based on the existing demo code) in MicroPython, CircuitPython, and Arduino C++
• Make a video on the FUFF MUX
• Create an item on Tindie 

These are all good stretch goals for Supercon. Even if the FUFF MUX doesn't win the contest, it'll still be for sale :]
