Package size comparison for PIC12f683

This is a quick photo to illustrate the three different package sizes I have for the PIC12f683 that I’m using in my Lego beacon. The rightmost (PDIP) is your standard, everyday, through-the-hole chip. The middle one is the surface mount 150 mil SOIC that is fairly easy to work with if you are careful. The right most two are the top and bottom of the tiny DFN lead-less package that I think I might have a go at using in my next prototype.
