check out CopperConnection

Max - I suggest you check out CopperConnection from robotroom.com .

Its a PCB drawing tool like ExpressPCB but exports Gerbers and Excellon files straight to OSHPark.

Small 1" 2-layer PCBs can be fabbed for $5, 4-layer for $10. Very inexpensive and easy way to fab simple shield PCBs. No Eagle size limits.

It looks like Copper Connection is just a layout tool. Is that correct? I'll take a look at it for this, but in general, I think I'd need the schematic capture integrated.

Duane - Yes, it is a layout tool ( manual drawing ). Similar to ExpressPCB's drawing tool. Great for simple breakout boards. I recommend the Eagle path for anything beyond that ( which requires schematics and autorouting ).  If you are willing to wait on OSH-Park, its a quick (effort wise ) and inexpensive ( $5-$10 ) path to making small interconnect adapter boards, etc that might otherwise be perf board or flying wires.

@Max, Duane

Were I doing this, I'd have a jumper next to each header / Screw terminal that you could select (with one of those little black jumpers that fit over pins).  More PCB space, but much easier to use.   I did a PCB graphic but I cannot get it into my post, I'll email it to you Max.

I await your email with dread anticipation, but .... you may have to wait longer than usual for a response, as explained in my blog Shut Down Your Email & Reduce Your Stress

David - I thought about doing that, but didn't want to add the additional board space. If I were to go that route,  I'd probably end up with a block of jumpers that would all all permutations of connection.

@David @Duane: As I recall we did discuss doing something like this -- but the header pin connectors protrude above and below the board (so as to allow for the stacking of shields), which means we need to have access to both the terminal pins AND the screw-block pins INSIDE of the header pin connectors so that we can connect them to the prototyping area...

@Max, Duane yeah. it is a tradeoff.  Given that most PCB terminals are 0.2 inch spacing, and the header pins are 0.1 inch, you could maybe put the jumpers between the header and the terminal bolocks, and stagger them so they don't take up too much space, but the board would then be that much wider.   ANd I suppose that once you have wired your jumpers, you're unlikely to want to change them very often.
