History
Werner Almesberger c75274fdc4 atben: rotated the CPU for much tighter layout; removed C9 
- atben.sch: removed C9 (only exists in Jonhanson's reference design;
  neither Atmel not Wuerth have it; in experiments, no effect was
  observed)
- atben.brd: rotated the transceiver by 90 degrees and redid layout
- atben.brd: aligned 8:10 card shape and antenna to metric (0.1 mm) grid
  and adjusted outline accordingly
- atben.sch, atben.brd: version is now 20110215

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)
