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"	2011-01-15 16:35:37 -03:00
Werner Almesberger	8d487739b7	atusd: removed resistor of futility ... - atusd.sch (R1): removed useless 0R resistor in clock path - atusd.sch (R2): renamed to R1 - atusd.cmp, atusd.brd: updated for above resistor change - atusd.sch, atusd.brd: set version number to 20110109	2011-01-09 20:36:29 -03:00
Werner Almesberger	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	2011-01-04 03:04:38 -03:00
Werner Almesberger	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	2010-09-12 00:27:10 -03:00
Werner Almesberger	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	2010-09-11 17:08:25 -03:00
Werner Almesberger	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	2010-09-08 17:36:47 -03:00
Werner Almesberger	dd999ebba3	atusd/: first try at a uSD-based board. Improved RF design.	2010-09-02 23:02:46 -03:00
