Werner Almesberger 7e20be97dc atben.brd, atusb.brd: set solder mask opening of fiducials to 2 mm
- atben/atben.brd, atusb/atusb.brd: set solder mask clearance of fiducials
  to 0.1 mil, so that the real solder mask opening has a diameter of
  almost) exactly 2 mm (instead of 2 mm plus 10 mil)

PCB manufacturing:

- do not print PCB edges on front/back copper
- do not print component values on silk screen
- note that the transceiver is "upside down"
- the center (!) of the board edge line marks the true board edge, e.g.,

                             Edge line (5 mil)
