The ATTO measures just 10.3 x 11.5 mm² and weighs 0.68 g. Nionics has equipped the board with an Atmel ATmega32U4 microcontroller, a micro USB port and a reset button. The company has pre-flashed the board with the Arduino Leonardo bootloader too. The ATTO is available to pre-order now for US$11.90 and will ship worldwide in October.

>:D Now you ll know if your Arduino programming is here to stay... 8)
The board quality looks quite bad.
And you can tell that from the picture ??? Get real dude !
What's the point of having a very tiny arduino board, if you then need a way much bigger (20x18 mm) adapter to actually use it?!?
Beside, this thing is quite expensive and offers no better features, with respect to other solutions already available...
