fungus:
...if you cheat a lot in height. I don't know where you got "12" from
no cheating needed. 12mm (1/2") is exactly what you get when you solder 2 sils to the sides of a dip. these measurements were made just now with metric caliper but rounded off to nearest mm. and it was obvious you were not trying to make a small pcb.
anyway to finish this discussion and get back to "tiny core" (im very interested also) ill say its silly to think ANY 14 pin breakout board will be bigger than a 28 pin regardless of chip package.
