62994dab86 atusd.brd: re-layout to slightly reduce size, and added more text 
- atusd.brd: rotated crystal by 90 degrees

  each other
- atusd.brd: reduced board length by 1.4 mm
- atusd.brd: chamfered upper left corner
- atusd.brd: removed "8:10 CARD" to make room for more important text
- atusd.brd: added "CC-BY-SA"
- atusd.brd: added silk screen text: "802.15.4", "qi-hw.com", "CC-BY-SA",
  and "by Werner Almesberger"

c0941dbe00 atusd: use crystal instead of trying to obtain an external clock from the Ben 
Known bug: didn't connect SLP_TR.

- atusd.sch, atusd.brd: replaced external clock with crystal
- atusd.sch, atusd.brd: increased version number to 20110115
- atusd.brd: changed "ATUSD" text on PCB to "8:10 CARD"

7b10db1bd3 atusd.brd: use 110% antenna; better follow 8:10 card shape 
- atusd.pro: changed ../modules/meander to ../ants/meander
- atusd.cmp: changed ANT1 footprint from "meander" to "MEANDER-110"
- atusd.brd: updated antenna, board outline, and dimensions
- atusd.brd: made board outline follow 8:10 card shape more accurately

6ee76112e9 atusd: switched schematics from the AT86RF230 to the AT86RF231 
- atusd.pro: changed ../components/at86rf230 to ../components/at86rf231
- atusd.sch (U1): set to AT86RF231
- atusd.sch: moved clock input from pin 29 to pin 28 (still XTAL1)

a2e91cf13e Take "pads" and "stdpass" modules from kicad-libs and remove local copy. 
- atrf/wpan-atrf.pro, atusd/atusd.pro, cntr/cntr.pro: use "pads" footprint
  from kicad-libs
- atrf/wpan-atrf.pro, cntr/cntr.pro: use "stdpass" footprint from
  kicad-libs
- AUTHORS, modules/INFO, modules/pads.fpd, modules/stdpass.fpd: removed
  pads.fpd and stdpass.fpd

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
