i wander how could it be to make something like a mega out of this little cutie hehehehehe.
do you think we can have something like a superarduino board out of this cutie ?

I think it might be helpful to describe what your asking.

We (friend and I) thought about it when AVR32 came out (and I have an AVR32 development board too).

So yes AVR32 could be used for a controller board like an Arduino, but why do it?
ARM, e.g. Cortex-M3 is comparable, available, cheaper, and made by several companies, including Atmel itself? Also their is an Open Source GNU C++ compiler for ARM, which is the same foundation as the AVR compiler.

Atmel make ARM Cortex-M3, as well as other ARM's

What is the benefit of the idea?

I would favor a upgrade to the Xmega series as a more evolutionary step for the Arduino platform. Same basic mega instruction set with additions and lots and lots of bigger better faster peripherals.

I fear a 32 bit Arduino path would cause a forking in the community and less contributions as a whole.

Yes, the XMEGA has some significant improvements over an ATmega.

I could be seduced by the fast 12-bit ADC and DAC.

On the the hand, ARM is comparable in cost, sometimes cheaper.
ARM versions with on-board USB end up being noticeably cheaper, though that hasn't shown up in board prices.
Some ARM have on-board ethernet, USB OTG, ...
Some ARM boot themselves over USB, and need no drivers installing on the host. They have driverless USB bootloaders manufactured in.

XMEGA two years ago would have been good.
But now NXP, ST Micro, Atmel, TI/Luminary, Cypress, ... have got some nice silicon. A friend uses PIC32 for everything, and loves it, and he is still a strong AVR fan, but PIC32 is better for his uses.

Don't get me wrong, I adore my Arduino's. I might get a good XMEGA Freeduino, if I found one I liked.

IMHO the technology is likely to fork if we don't support both lower cost and higher performance, and both of those can be done with ARM.  I'm looking at ARM, and porting the libraries. I think the core work will be done before year end anyway, without my help.

But, It is nice to dream  ::)

If the community grows a lot as a result of a wider range of capabilities, a fork may be okay.

If the 32 bit boards were cheaper than existing Arduino's (which appears to be feasible) then maybe AVR's would become the minority.

The major downside of ARM is the lack of dual-in-line through hole parts. If that were fixed, at reasonable cost then things would get closer. DIL ARM parts with USB included would give me a stronger reason to move. I look at those PIC's with USB in DIL packages, and wish Atmel would make some too.

it seems the majority is voting yes ... maybe it is not a bad idea after all...

Hi. Total newbie here.
I'd probably buy one if all the headers were on .1 inch centers :(
