its basically set up like arduino. Has an IDE you can get from Leaf Labs

I've been recently dabbling around again with arduino projects. More importantly digging into the study of C++ language to help understand better how to code for the arduino and other uC's.
$14 for that dev board is dirt cheap!
just thought I'd pass on the find... I remember Mike mentioning about trying to build a new voice using this uC. I'd like to see it happen and might be able to lend a hand with the code when I get more familiar with C++
