Question on processor used by Seeeduino Mega ...

What processor does the Mega use? Is it the 1280 or the 2560? Did all versions of the Mega board use the same processor? Looking at the various doc sources (i.e. the Seeeduino Mego Wiki & the web-page), it appears undefined. Some places say 1280 and others 2560. I know they are bot in the same atmel family and I’m guessing that’s where this confusion comes from. My gut feeling says it must be the 2560, since it has 70 I/O & 16 ADC channels which the 1280 doesn’t support. Just want to be sure …

Thanks,
Chris

It uses the 2560
