OXC LPCorrector - A LPC Rebuild QSB

I was asked to make a QSB for rebuilding the LPC debug port for 1.6 consoles, now that I have a board on hand I figured I would ask for feedback on the board and any changes that I should make.

Edit: Forgot to mention that once I make the changes and they're confirmed to work the gerber files will be available so anyone can order one.

I made a imgur gallery of pictures of it installed https://imgur.com/a/RzeNhiv
But here's what it looks like


I also included a PDF that shows the current design.

A bit about the board itself and what changes I've made so far.

• The castellated edges line up with the test points quite nicely I don't think I could really improve them much as is, manufacturing tolerances and all that.
• I've slightly moved the pin header holes and slightly enlarged their pads to try and match them up better to the Xbox. Although I'm not sure it'll matter much, again tolerances and all that.
• I've made the cut-outs a little larger to give more clearance to those resistors. I've also changed the overall board outline a bit to make those thin parts a little thicker.
• I changed that GND pad to be the same size as the D0 pad.
• I've done what I can to impedance match the traces to what I suspect the corresponding traces on the Xbox are, somewhere in the realm of 50-75 ohms. This is probably overkill but why not? In order to do this I used super thick traces and a GND pour on top with a couple of traces on the bottom to stitch the GNDs together. I tried to place those GND traces away from any traces on the Xbox itself and put the vias away from any test points. Even though they're tented that doesn't always work.
• The OSHpark board is 0.8mm thick which is probably the max thickness, a 0.6mm PCB will work much better.

So yeah any thoughts or ideas?

 

Add the "1.6" to answer the question in 10 years when someone comes across one in the wild.

XBOX 1.6
LPCorrector​

 

Good point, technically it'll say OXC (Open Xbox Community) 1.6. Although it would probably be better to go

OXC
XBOX 1.6
LPCorrector

or something like that.

Even though the files should come with all the info about the board as well as the gerbers, but that's pretty much guaranteed to not happen at some point.
