and the files. Could use some feedback re: pin header labels - can't really squeeze things into the middle, the '644 placement is fixed by the ICSP header.
I suppose one way is make the board taller, slide everything up a tenth or so and out the labels around the outside.
Am using this neat little FTDI module vs the FTDI chip itself - figure the cost of the module and its parts is comparable to the chip, USB connector, some caps, and the hassle if soldering that chip in place!
I made it a little wider, cleaned up the right angle traces, added header pin names.
Think the names are too big this way?
[edit- fixed couple typos in the link]
This is a really nice board. The FTDI part you found is great because it's cheap and has extra fun pins too. Problem is, it's not compatible with the usual FTDI cable. The cable and the Sparkfun 'basic' boards all use a common pinout, like the Sparkfun Arduino Pro and friends. I would say more people are going to have the Sparkfun units (adafruit sells them too). So I'd recommend a simple 6-pin header using the FTDI cable pinout. FTDI Friend with Micro USB Port + extras [v3] : ID 284 : Adafruit Industries, Unique & fun DIY electronics and kits
Definitely needs the pin labels, good to see those come in.
How about mounting holes on the corners now that adding up labels created more white space?
"Problem is, it's not compatible with the usual FTDI cable."
It's not meant to be - this part will plug in instead. Then a standard USB cable can plug in.
And if your application doesn't need permanent connectivity, don't install it.
I suppose I could put holes in parallel to plug a FTDI-Basic onto also for another option.
Nono, what I am saying is that many of us have an FTDI cable, or other compatible product, around. If there were headers for connecting that then we wouldn't NEED to buy this additional $10 part.
Okay, I am calling it done pending any review comments - just waiting on FTDI module delivery to confirm fit (has already left Mouser).
Also added FTDI-Basic/FTDI Cable holes if someone prefers to use one of those for downloading sketches & then removing it.
Added extra labelling also to make it easier to find "the good pins", those with the extra features.
Think all parts sizes selected should be pretty easy to hand solder without hot air & reflow techniques.
Gotta go find a protoboard I have somewhere & confirm the headers are correctly placed. I copied the positions from the Duemilanove file and made everything else fit around them so shields should fit. Also added the new SCL/SDA and power header pins.

I'm not sure the ICSP header is in the correct place to work with the Ethernet/SD card.
Well, I took the position numbers from the duemilanove and put them into this card. The whole groupw was then selected & moved so doing a one to one comparison requires a little math now.
I think it may look funny due to the big chip being there and the analog header being 2 pins longer.
I am pretty sure the end pin of the D0, the end analog pin (3rd pin now) and the inner row of the ICSP pins line up, so its just a question of spacing between the headers. I am looking for a prototype shield I have that I can lay over a printout to confirm.
Hmm, that's not what I have now is it - rats, something got moved unintentionally. Looks like the reset button ended up where the ICSP header was supposed to be.
Back to the drawing board!
Here are some pictures of the new board that arrived in the mail today....
I have a few details on my *uino-1284p page. The source files are on Github. Now I am waiting for some parts in the mail to see if this puppy will work.
Had those made by iTead. Interesting that the box from iTead is identical to the box from Seeed. But the little flyer that came with it is different. About 2 weeks from paying and emailing files to receiving the boards. I'd say that turnaround time is outstanding.
Not bad. US Customs must be a little slower, mine have taken a few days longer.
They accepted the Leonardino design on the 9th, boards shipped the 13th, waiting on delivery.
Status is it left Hong Kong on 17th, so its moving along.
I'm sure that ISP header is in the wrong place, the inner 3 pins should be in line with the end of the standard headers (ie the standard A5 and D0 although your pinout on the A header seems to be different).
