NEWS!
After a long time I came back.  smiley-grin
I'm redrawing all cards with a new graphics. For those who follow me on twitter is not news!
Here the pinout of ATMEGA2560 shortly the Mega pinout

Hi All,
as promised, after the version of arduino uno, here is the diagram of Mega:

NEW Version 2.0

Download Arduino MEGA v2

(old versions)

Drawing is 1:1.



for those who asked me, the version with the pin number (not 1:1)



and the Pinout of ATMega2560



Download as PDF, PDF with pin number
and the ATMega 2560 Pinout PDF.

This is a "beta versions" then any suggestion or correction is accepted.  smiley

I've updated the diagram. (First post)
I'm checking the serial because there is something wrong ...  smiley-kiss

Power limit is incorrect - its 200mA per VCC or GND pin - there are 4 of each, so 800mA would be the MAX.

Other chips are the same too - 200mA per VCC/AVCC pin, the total load spread over the ports supports that.
See the  "Electrical characteristics" section of the datasheets.

See the  "Electrical characteristics" section of the datasheets.

We have discussed this before without reaching agreement as it seems to be based on how one interprets the datasheet. I'm still of the opinion that no AVR 8 bit chip would allow a total device current draw of 800ma and have never seen that total number (800ma) used in any avr datasheet.

Take the 328P for example.
Datasheet in electrical absolute maximum ratings section:

Quote
DC Current VCC and GND Pins................................. 200.0mA

Note they say 'Pins' not Pin, so I feel the 200ma value is the maximum total chip current consumption limit.

Comments from any welcomed, I was wrong once before.  smiley-grin

It's a beautiful thing!  I had recently Googled for the longest time and found some pics of pins, some pics of pin numbers, and still other with different bits of info.  This is what I had been searching for.  Everything in one place.

Thank you!!!

Hello!

I Love your work and the help you give us !!! Thank you

May I would suggest to add the PIN numbers as they are printed on the PCB (you did this on the UNO Reference), this would be easier to use if you don´t screw your Arduino to the printout smiley-wink

Thanks in advance
