If you do re-do it, should toss in the ethernet jack while you're in there. How different is the pinout between the 3X and the 3U?

A problem with this is that it's not just the ethernet jack.  You also need an ethernet PHY chip, which usually has its own crystal, and a relatively "serious" interconnect to the main CPU...

Yes I think Ethernet wouldn't fit, maybe I could squeeze in 1 or 2 more resistors :)

@UnaClocker
I remember it was enough to force a complete redo of the PCB, but I'll have another look.

The 3U and 3X are totally different pinout wise so it's a complete redesign of both PCB and partial redesign of the schematic because the 3X has at least one extra feature (the DACs).

So unless there's some real interest (unlikely) that's all folks :)
