Does the SPI flash have the right footprint? @samchoy88 is this the footprint we should use? I think I bought a larger package for this chip, but I think we should use the smaller one that fits this footprint. screen shot 2014-12-21 at 15 56 49

The distributors that I talked to in China recommended the larger size flash as being more common. There seemed to be ok quantities (>200pcs) in stock for both varieties from Digikey et al.

Makes sense. When I ordered the chips in Huaqiang Rd they just gave me the large ones and didn't even ask which size.

charlespax commented 9 years ago

@samchoy88 can you put the larger footprint in 0.9 PR should we push it to 0.10?

samchoy88 commented 9 years ago

I found the original component pin assignment in library has problem.

charlespax commented 9 years ago

Wow! That's a crazy error. Awesome of your to catch that :-)

The T400 should use the larger footprint. I believe it should match the parts I gave you. I'm pretty sure the footprint on the board is the smaller package.

Updated library, schematic and PCB layout.

Cool. That's the sort of thing what would have made this revision buggy as hell. I think we can close this.
