CrossRoads:
You guys make it sound like I need to get the prototypes ordered yesterday!
No, but you have seemed to have created an itch in a lot of us. I'm still not convinced that all the software hurdles have been leaped over yet, clock @ standard 16Mhz, bootloader compiled to run at 16Mhz, etc. Pin mapping should be the same as 644p however.
I'm glad you are still considering the manual Vs auto-voltage switching function. Can live with either but still think the board space could be used for more useful purposes.
