Are editable schematic and board layouts available?

I’m designing a board to add a second channel for XY mode (and a couple of other things; RS-232, 3D compass).
Since the DSO Nano was open source, I assumed that the Eagle (or whatever) schematic and PCB layout files were available.

I’d like to use the same layout for the 2nd input channel, to give it the same characteristics as the first channel,
so I’d like to start by modifying the existing board design… but I can’t find that anywhere.

It’s not a big problem, I can re-create the layout, but I thought I’d ask if anyone knew where I could get it?

I don’t want to use the DSO Quad, because the FPGA is unnecessary for my application (and requires a $1500 investment
in software!); I need relative radio silence and long battery life so want to limit the amount of high-speed digital hardware.

From what I can see here, FPGA development does no longer require a $1500 investment in software: (search for “Lattice”)

And did you see what Petteri (jpa) made here? viewtopic.php?f=22&t=3239
It is amazing! Having something like this on the DSO Nano would be fantastic.

Sweet! I’ll see how I go with the V2 first; still have power and noise constraints. But the Quad would make a nice SDR, with the right front-end.
