- 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)
