Hi! I have a suggestion concerning the pin spacing between D7 and D8: remove it or accentuate it so that the pin spacing becomes standard with generic proto pcbs. I understand that this would become a problem with current shields, but it would make prototyping easier for those of us who have no access to etching our own pcbs. Thanks
i second that, i see no reason to repeat a mistake
In my Arduino Runtime board design I joined both Digital I/O headers to make the pins breadboard or protoboard friendly.
