I finished cleaning up the part designations on the printed circuit board.

I also finished the Bill-of-Materials and the cost of everything for a one-off production run is ~$40 using Elecrow as the board manufacturer and Digikey as the components supplier. There is also a cost of $70 for the educational version of the Segger J-Link from the Adafruit website. This has been added to the files section.

Is there anything you'd like to see added to the design? Let me know in the comments!! I'd love to hear your thoughts.
