Jan made the right decision to include Mouser P/Ns in his BOM spreadsheets. So I compiled them into Mouser format spreadsheets -only up to 30 component P/Ns each- and gave the order (**).Where did you find all the parts? They are not currently available.
I think I mention the location of the USB connector, or at least in a pic.
The several caps you highlighted have their designator on the top board, and you can't see that anymore after you place the connectors. My bad, sorry.
