Hi Guys,

I was contemplating on the difference between the original ATmega2560 board (shown in blue in the diagram) and the main controller board that comes part of APM-1 (which is in red). I see this this APM-1 red board DOES NOT have a USB cable attached, whilst the blue one has a USB serial socket.

Original Arduino ATMega2560:

My APM-1 controller board: (This one is different)

The pins are also different in both. Can someone show me why is it so, and the difference.

Thank you very much.
