So I use ExpressPCB for my designs (see image), but I find that it's kind of basic (note the red box labeled "ARD" on the right side). I'm looking for an alternative that might be a bit more robust (and has an Arduino part built in!). Having multiple trace colors (besides the three layers in ExpressPCB) would be a definite plus. So far, I'm looking at Fritzing and KiCad. Any suggestions? Cheers.
