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.
One more thing: port C.29 (PWM10) is high current.
Could you also move the comment on the left "Allows serial2 to be used for SPI" above the "SCK1" box. This to make the total picture a bit less wide (as such fits better in a document).
Anyway I would like to thank you for a super job done. This is a great diagram to be used for all (hey Arduino guys, please take note
Great work so far. I have a suggestion: I printed the diagram out, and there's a problem that in print there's a lack of contrast with the yellow-on-grey port pin labels - they are almost unreadable. Given that (for me anyway) that's the most important column on the diagram could you change the colours for something more high contrast?
On pin 10: As you note this is also connected to port C29. Port C29 is referred to as digital pin 77 in Arduino - that is, if you load the Blink example and change the pin to 77, it will blink an LED connected to pin 10. It might be worth noting that as well.
Also could you add digital 'pins' 72 and 73? These aren't physical pins, but they are connected to the RX and TX LEDs near the native port - changing Blink to use pin 72 or 73 will flash them. Ports are C30 and A21 respectively.
