Arduino Mini 05 (Original)

This is the new, smaller, Arduino Mini 05 with ATmega328. The latest version of this board is built around a smaller ATmega328 package, allowing all of the parts to be populated on the top side of the board. Of course, it still requires an external serial connection for programming.

The Arduino Mini 05 is a great development module for building compact devices that need to interact with the world around them.
