40 lines of IO plus a number of the Arduino's lines brought out to header sockets. A couple of status LEDs and we're done. I've taken the PORTC lines, AKA the analog inputs A0-A5 and D2-D7 to the back of the board. As it is, the shield's pass-through connectors are offset by 50 mil, making piggy-back boards impossible to make cleanly out of proto-board. The power lines and D8-D13 have their pass-throughs in place, as they are essential for my MMC sail.
The Linguine Layout:
I love kynar wire! Did I ever mention that?? :D The enamel coated copper wire is great too.
The EEProm Topper:
This is a a scavenged megabit chip. My first application for this board will be to program this. As it slots into the IO card so it will fit into a small adapter board that I have in mind to enable it to emulate a 64k ROM to transfer code to my burner.
The Assembled Wedding Cake:
Silly! But that's what I like about it. An antidote to the misery happening in the world today ;)
