It is fairly easy to look at the reference design and the layout and just scribble down a BOM. N'est-ce pas?
The Arduinos, as much as we love them, are not terribly complex or stringently specified devices. If you see where they show a 1K resistor, pretty much any 1K resistor will do. or, if you have it a 860 ohm will likely do, or a 1K2. Etc...
