I'm working on a design shield and have a "tricky" dimensional question. I don't have a Duemilanove in front of me to test, though that's the platform I'm ultimately designing for.
Here's the problem: I need a coin cell on the shield, but I want to put it on the "bottom" (the side that faces the Arduino) to preserve space on the "top" for other components.
It looks like clips for 12mm cells are available that are 2.34mm tall. Is there enough room? It looks like there would be enough room up by the digital headers, but since I can't actually measure, I'm not 100% sure. The holder is 13.2mm in diameter.
Short of me ordering a Duemilanove and waiting a week or two, can someone let me know if this would fit? Anyone done this before?
