I just sent the PCB to be fabricated by Seeedstudio. I also received the stencil today.

I added the BOM as a CSV file. Quick note, all of the component except the microcontroller are available from Digikey. Other websites like Mouser have the microcontroller, but miss other components, although equivalence might be available. The BOM is also available on Octopart at https://octopart.com/bom-tool/qB575L1h.
