b3374dd7c8 Added antenna tuning "tail" suggested by Joerg. Made board slimmer. 
- modules/meander.fpd, atusd/atusd.brd: added tuning "tail" to antenna
  (suggested by Joerg Reisenweber)
- atusd/atusd.brd: pulled back somewhat protruding CLKM test point
- atusd/atusd.brd: made external board 20 mil narrower
- atusd/atusd.brd: version number is now 20100912
- atusd/atusd.pro: KiCad commit noise

5d28e1b182 Corrected small footprint errors. Made 0R "inductor" a resistor. 
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: made L1 a resistor
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: changed effective
  footprints of components erroneously using 0805 to 0805-M
- atusd/atusd.pro: commit noise

f17613bc69 Applied clock voltage divider fix and corrected too closely spaced via. 
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: changed resistive
  clock voltage divider to capacitative
- atusd/atusd.brd: moved via near pin 1 and rearranged ground planes
  accordingly
- atusd/atusd.sch, atusd/atusd.brd: bumped version number to 20100911
- atusd/atusd.pro: KiCad commit noise

3533e0463c Found out that we can't share MISO and MOSI after all. Redesigned the atusd 
board.

- atusd/atusd.sch, atusd/atusd.brd: separate MISO and MOSI and free the
  extra signal we need by no longer connecting SLP_TR to the host
- atusd/atusd.sch, atusd/atusd.cmp, atusd/atusd.brd: removed reset circuit
  Power-on reset seems to be sufficient.
- atusd/atusd.brd: improved AVDD ground plane
- cam/pcb.pl (rot): cut counter-clockwise to reduce burr
- cam/pcb.pl: advanced origin for 2nd run

fc0acf1787 Assorted small layout improvements. 
- atusd/atusd.brd: tightened routing of nSS and XTAL1 net to improve ground
  place coverage
- modules/0805-6.fpd: widened pads for easier manual soldering (note: this
  is still ad hocery)
- atusd/atusd.brd: use thinner track to connect feed line to comply with
  DRC
- atusd/atusd.brd: version is now 100903
