Anyway, it looks like regardless of which flavor of Arduino clone (either a RoboDuino or a WiseDuino) I get, I will need to create some sort of shield to go with it. They are the same price in kit form, which is what I would get.
For the RoboDuino, I would need a shield that can attach below it that has the RTC, battery backup, EEPROM, and anything else I think I might need. For the WiseDuino I would need a shield with the 3 pin headers for all the I/Os, I2C header, and anything else I might want.
I am just starting to learn Eagle, and have gone through the Sparkfun schematic tutorial and have that part down pretty well. However, I am having difficultiy with the PCB creation tutorial. It does not make sense to me at all. It seems like some steps are left out, some setup isn't correct, or something else is wrong, but I can't seem to complete the operations using the latest Eagle v5.6. I can't even get the right of the grid to snap to a 0.1" mark. I have no idea what I am doing wrong here and need some help.
I very much want to learn how to make my own shields for the Arduino and compatibles. I've already figured out how to build a shield so it can attach on either top or bottom of an Arduino workalike, so will build the controllers from kits in order to arrange shield headers the way I need to have them. I may even replace the headers on my regular Arduino USB Board to make sure my scheme actually works.
