Check out the following changes to make a more reliable PCB. Those are minor cosmetic changes, but ease your life to avoid short circuit. + +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. + +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. + +3. Exporting all the parts in the proxmark3 Eagle Layout into a library for minor silkscreen edition: proxmark3_components merged.lbr + - Editing components footprint as was overlapping with top stop mask + +4. Adding top, bottom, in1, in2 layer markings in PCB layout for better manufacturing identification + +5. Generating 4 layer CAM files
