The pin usages are not all defined as you will see but that is the best list of shields.

Some shields are still on my list to add too.

If anyone wants to find out what all the pins are on all the shields then I will happily add it on/create a table for it.

The problem is that often, that info is not stated, they just work. If you want to know what pins they use, you have to work it out.

Thanks for that list Mowcius.

I've tabulated that, looked at a stack of schematics, and generally faffed around to come up with this.

Coding badly: I've done the ones from the Arduino site as well, although most were also on Mowcius' list.

Many still have ? in their row, sometimes this is because there doesn't appear to be a public schematic, with others it's because I had to download a ZIP and haven't got around to extracting the schematic yet.

I've had enough for the moment, gone cross-eyed looking at this lot. But if it's worthwhile I can verify more over time, or maybe others can chip in or the owners of these boards can tell us exactly what pins they use.

Well I can trust it when I'm not on my computer  ;D
I have saved that, looks very nice, just need a way to get that as a nice looking table on a website now. If I get the time, i might see what I can come up with.

Well if we can get some kind of permenant web-based version (not google docs...) then it will definitely be useful to a lot of people.

Thanks Mowcius,

A lot of schematics just have signals coming from small 1, 2 or 4-way headers with no real indication of where the signal comes from. You would have to check out the PCB to see where the header is physically located.

Also many schematics show all the Arduino signal names on a header but don't actually use them so you have to trawl the schematic looking to see if the signal was used or not.

Still it's a start, treat it with a grain of salt for the moment, but if you can figure out how to present it on a web page when we're happy that it's pretty right it would be a useful resource I think.

When/if you get around to it, may I suggest a "verified" column that indicates that the info is almost certainly right.

Sounds like a good plan.  :)
