PCB schematic for Arduino Mega

Hi, I am looking for a PCB schematic of Arduino Mega 2560 Rev3 (preferably something I can open in Circuit Maker).

Currently, I am attempting to make a PCB shield of sorts that I can insert onto the Mega. I have designed the relevant circuitry on Circuit Maker. But I want to make sure that the male header pin positioning on the PCB exactly matches the female header pin positioning on the Mega. Hence, does anyone know where I can get a PCB schematic for the Mega that I can use?

Do a Google search for;

'arduino mega'

You should see a link to the arduino mega board on the Arduino store website.

The schematics will be found on the 'documentation' tab.

PCB layout is in Eagle.
