Product Code: DFR0225


Romeo is an All-in-One Arduino-compatible microcontroller from DFRobot especially designed for robotics applications.  The Romeo benefits from the Arduino open-source platform, it is supported by a very large community of tinkers and hackers, and their work is typically open-sourced, and the Arduino functionality can easily be expanded with Arduino shields. Romeo has an integrated 2-way DC motor driver and wireless socket allows you to start your project immediately without the need for an additional motor driver or wireless shield. 

The Romeo V2 behaves like an Arduino Leonardo, it's based on the ATmega32u4 chip, you can program it directly from the Arduino IDE version 1.0.1 or later.  The 32U4 handles the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, etc, using the USB-HID protocol!  The best advantage is that ATmega32u4 has two serial ports which allows you uploading sketches without removing wireless modules, which makes debugging a lot less painful.

We've also improved the power circuit in the Romeo V2, it has now a switch to select power source either from USB or external power. 
Please note: The analog sensor port pin mapping on Romeo v2 is different from the old version.  Please select Arduino Leonardo board when using Arduino IDE.
