Hi, preliminary schematics are available as PDF at >
http://downloads.qi-hardware.com/hardware/milkymist_one/sch/20110511/rc3_design_20110511.pdf To do: > * Remove text "TODO: depending on PCB routing difficulties, add an > expansion header and connect as many FPGA spare I/Os as possible" > (this was already on RC2) > removed > * Move J21 so there are no unnecessary connection dots on the schematics > (this was already on RC2) > done > * Update the HW_VER resistors to indicate PCB revision 2 (place R177 > alone) > R177 placed, and R176 DNP > * Leave the old names SW1, SW2, SW3 for the pushbuttons - that's how > they are named in FPGA design, low level software etc... let's only > rename them in the GUI and case > changed back. > * Remove the "S2" text in the pushbuttons (this was already on RC2) > removed. > * Name other pins (1 and 3) of the reset IC symbol > added. > * Maybe reduce the capacitor values at the video input (470pF)... I used > those from the Altera DE2 board, but in hindsight, they are pretty > large. Perhaps some 100-200pF would be more appropriate. This could > explain why we have to crank up the contrast and luminosity a bit... > C202 ~ C207 now are 120pF. ref.: http://en.qi-hardware.com/mmlogs/milkymist_2011-05-10.log.html > * Protection circuit and ferrite beads still to be sorted out. > D14, D15 5W 5.6V Zener diodes, F2 MINISMDC200F-2 added, removed L11 1206 bead. Also F1 removed in USB schematic. ref.: http://lists.milkymist.org/pipermail/devel-milkymist.org/2011-May/001508.html Source: http://downloads.qi-hardware.com/hardware/milkymist_one/pcb/rc3/051111/rc3_design_20110511.tar.bz2 With regards to individual footprints and routings is moving on. There's text on some component in PCB Library(MilkymistOne1.PcbLib) should not be there, which I am working with house though, you can just temporarily view the dimensions firstly. Thanks, -adam
