Introduction

RoMeo is an All-in-One microcontroller especially designed for robotics application. Benefit from Arduino open source platform, it is supported by thousands of open source codes, and can be easily expanded with most Arduino Shields. The integrated 2 way DC motor driver and wireless socket gives a much easier way to start your robotic project. 

The most important about this board is that it is Arduino compatible which means you can use Romeo as a standard Arduino Nano board.
