EAGLE is free up to a certain board size 3" by 4" if I remember correctlycertainly big enough for a shield (unless it "hangs over the edges" a lot!)ah just saw your not "not for profit" - oops
The cheapest eagle fee is 50$ to use it in commercial projects, so that might be the sale of half a dozen of shields or even less..
Doesn't internal R&D qualify Eagle to be used? You're not making money out of it and if eventually goes into production, you can always buy the Eagle license.
Does anyone here use anything other than Eagle?
