Werner Almesberger	57874cf5e2	Revert TVS size reduction. We're not ready for it yet. ... - cntr/cntr.sch (VR1, VR2, VR3): reverted change to 0402, because this would be too difficult to route with current board - cntr/cntr.sch (VR1, VR2, VR3): change voltage from 5.6 V to 5.5 V, for compatibility with selected part - cntr/cntr.brd: updated for value change	2010-10-24 23:55:37 -03:00
Werner Almesberger	021bb00e96	Cleaned up component values in cntr schematics. ... - cntr/cntr.sch: LED part number is LTST-C190KRKT, not LTST-C190KTKR - cntr/cntr.sch: changed Vdc of VR4 from 5.6 V to 5.5 V (to match EPCOS CT0603M4G - cntr/cntr.sch: changed VR1 through VR3 to 0402 for lower capacitance	2010-10-24 19:43:53 -03:00
Werner Almesberger	c1b7b81936	Added title, author, and revision to all schematics and layouts. ... - atrf/wpan-atrf.sch, atrf/usb.sch, atrf/atrf.sch, atrf/wpan-atrf.brd: added title, author, and revision (100820) - cntr/cntr.sch, cntr/cntr.brd: added title, author, and revision (1)	2010-08-25 19:42:46 -03:00
Werner Almesberger	81ab679fbd	The parasitic capacitance of the three probe input pins and R1 formed a ... quite formidable low-pass filter that almost completely eliminated the 1 MHz signal. - cntr/cntr.sch, cntr/cntr.brd: changed R1 from 100k to 1k to increase input bandwidth	2010-08-25 06:36:02 -03:00
Werner Almesberger	5553d3e75b	New circuit: an arbitrary-precision counter. ... - BOOKSHELF: added the C8051F320 (alias "f320") - BOOKSHELF: added "atrf" alias for AT86RF230 - BOOKSHELF: added "f326" alias for C8051F326 - AUTHORS, components/INFO, components/c8051f320.lib, components/c8051f320.dcm: added Silabs C8051F320 - AUTHORS, modules/INFO, modules/Makefile, modules/qfp.fpd: added LQFP32 for C8051F320 - cntr/cntr.pro, cntr/cntr.sch, cntr/cntr.brd: arbitrary-precision counter	2010-08-22 21:32:54 -03:00
