- c2ben/c2ben.sch: rename VDD net on the header board to VBUS, to prevent
KiCad from considering it to be the same as VDD(nPD02)
- c2ben/c2ben.brd: make board 40 mil wider to have more room for applying
isolation (silicone paste)
- c2ben/c2ben.brd: reduce distance from header pad to board edge by 5 mil
to 40 mil, to increase overlap of pins and pads
- c2ben/cam/pcb.pl: adjusted board size and spacing between boards for
above changes
