I am thinking that the Pro Mini can plug into a standard 24-pin IC socket… with the addition of some pins on the Mini board. Is this in fact the size of the Pro Mini and the pin spacing?
It doesn’t look like it will fit into a standard socket, I was able to get in on a breadboard, but instead of sitting on the inner rows of the board, one side is on the second row, and the other side is on the 3rd row. So you should be able to get into a breadboard, but its about twice as wide as a standard DIP chip.
It appears to be spaced at 0.7" compared to a wide dip package of 0.6" if that helps…
Just to follow up with this… I got a PC board made a day or so after I posted this before I got a reply. I used a 24-pin wide DIP for the spacing and it fits fine on the board. I did not properly account for the end for the programming adapter (blk … grn) which extends outside of the ordinary 24-pin DIP boundaries.
Oh, well. Some other things needed to be changed from the first prototype board anyway.
