<p>Oh also Arduino is launching an official Arduino board based on the SAM3!<br>

So it would be nice hardware for prototyping.</p>

</div>@scanlime also used a Propeller for a similar scale project:<br>

Not too much there about the GPIOs, but I found the discussion of system<br>
architecture for high speed IO very enlightening.<br>
