I would prefer that it would scale/fit on an A4/Letter papersize
At present it needs an A1 sheet, how large is your printer But it's all vector based so should scale to anything.
VIN, do that pin give the same level as the input?
VIN is the same everywhere, if you have 12v on the barrel jack you'll have 12v on the header pin. That said, if you're drawing a lot of current it would be better not to run it through the PCB.

Yeah, that was just a quicky at hi-compression to show the new design, and the PNG was too large.

Wops, I haven't read it as VIN, I have read it as vcc :), thank god I have used only usb power, and breadboard psu so far
No idea, probably becaise SCL1 and SDA1 are the standard I2C signals and old shields don't expect pullups, whereas SCL and SDA are new so thay can ba added.
Turns out the datasheet I was looking at is only the Summary data sheet - only shows the 100 & 144 pin packages. Didn't realize there was a 217 pin package as well.
They are on the schematic so at some point someone decided to at least label the nets. There's no mention of a second CAN on the product page so it looks like it's not yet supported and I've left them white. Likewise for the fourth USART and I doubt the SPI ability of two of the USARTs will ever be supported, but I think some people may want to use that one day.
BTW, does anyone know if the power jack is a 2.1 or a 2.5mm type?
If you look closely you can tell the difference. The native port has a micro AB socket which is more rectangular. The programming port has a micro B socket which has diagonal bottom corners.
neslekkim:
I guess you are going to mark the usb ports also? which is native, which is programming, strange that they are not labeled on the board..
Yes, I wondered, too. Then I turned the board over ....
Actually, I checked under the board now, There is no marking for the usb plugs.
Begins to wonder if Arduino.cc shipped discarded units to Adafruit?, to much changes between this one, and the one everyone else got.
