I've spent some time looking over the proxmark3 hardware design and the bill-of-materials and updated it to current part numbers on DigiKey. There are some discrepancies for some parts which I'm sorting out at the moment, so I don't promise that this BOM is entirely correct yet. C35 for example is listed as 50pF on the schematics but 100pf in the original BOM. C37, C38 are listed as 220uF on the schematic but 100uF in the original BOM. Who knows, maybe I'll notice more, the more I look.
