Looking for some advice, my current project has outgrown the 328's pins but I want to keep with DIP packaging.
I was originally looking at the 644p but the old sanguino website has gone, was there ever "Official" support for the 644p?
Failing that the ATMEGA1284P is only bit or so more expensive, although im not keep on the overkill, its the pins I need not the memory space.
Long term i need to be able to program and use on breadboard/pcb so im looking for a very lean implementation that doesn't rely much on a certain board.
I Also want to use an existing Uno as a programmer.
The end product if i ever get anywhere with it, will be a little cost sensitive so would prefer the 644p even a bit makes a difference in volume!
