Hi, > Pls commment this newest routed file. Thanks.
* WTF is J22 (and R59)? Unless it has a good reason to be there, please remove it and restore the previous VGA routing. * FPGA decoupling: place the 0402 1V2 capacitors closer to the center. The larger 0805 capacitors can go further away from the center. For example, C53 and C54 should be moved somewhere else and their current position taken by 0402 capacitors. Move as many 0402 1V2 capacitors as possible under the FPGA and close to the center. * OK not to change the few remaining shared power vias. At least there is no via sharing anymore on 1V2 which is where the worst bugs could occur. * New small addition: please indicate "Not 5V tolerant" near J21 (GPIO expansion) * I can't find the footprint "SO8-10-2.54" for the optoisolator in MilkymistOne.PcbLib - please add it. Also, link the footprint in MilkymistOne.SchLib like it's done for other parts. * What is the reference document you used for making the optoisolator PCB footprint (so I can check it)? Is it the Fairchild datasheet that you've linked in the BoM? In this case I need to update the milkymist-datasheets repository that contains a datasheet for Vishay parts with different footprints. * You do not need to add that many 100uF capacitors on the DRAM. It's mostly high frequency noise that we are filtering. Use only one extra 100uF per chip instead of 4. > c) Current soucring status is here. > http://en.qi-hardware.com/wiki/Milkymist_One_RC2_BOM Have you updated the prices as well? > d) To be done later: > http://en.qi-hardware.com/wiki/Milkymist_One_run_2_schedule#Packaging_Parts_Accessaries > Anti-Static bags, box and positioners. Contents the box: * MM1 board * JTAG adapter * 5V power supply * leaflet (print the MAC addresses on it?) * USB cable for the JTAG adapter (do we include one or assume people already have it)? * Fedora USB drive?
