Romeo is an All-in-One Arduino compatible microcontroller especially designed for robotics applications. The Romeo benefits from the Arduino open source platform, it is supported by thousands of open source codes, and can easily be expanded with most Arduino Shields. The integrated 2 way DC motor driver and wireless socket allows you to start your project immediatly without the need for an additional motor driver or wirless shield. 

The Romeo behaves like standard Arduino Duemilanove 328 which means you can program it directly from the Arduino IDE
