   3 Main problem: more then 800 DRC errors when runing that in Eagle. Check out the following changes to make a more reliable PCB. Those are minor cosmetic changes, but ease your life to avoid short circuit.
   4
   5 1. Eagle Layout / DRC rules / Masks / Limit: from 0mil to 16mil, thus ordinary GND and signal vias which smaller then 16mil wont be open at solder stop mask layer.
   6
   7 2. Eagle Layout / DRC rules / Masks / Stop MAX: from 2mil to 0, this way the solder stop mask wont overlap silkscreen drawings. Also as per PCB assembly houses, it's recommended, they set their own scaling for production.
   8
   9 3. Exporting all the parts in the proxmark3 Eagle Layout into a library for minor silkscreen edition: proxmark3_components  merged.lbr
  10         - Editing components footprint as was overlapping with top stop mask
  11
  12 4. Adding top, bottom, in1, in2 layer markings in PCB layout for better manufacturing identification
  13
  14 5. Generating 4 layer CAM files
