RoMeo V2[R3]is an All-in-One Arduino compatible microcontroller especially designed for robotics applications from DFRobot. The Romeo benefits from the Arduino open source platform, it is supported by thousands of open source codes, and can easily be expanded with ArduinoShields. The integrated 2 way DC motor driver and Xbee socket allows you to start your project immediately without the need for an additional motor driver or wireless shield.
Another improvement of Romeo V2 is that it supports stepper motor control. Use this library.
The RoMeo V2[R3] behaves like Arduino Leonardo based on the ATmega32u4 chip, you can program it directly from the Arduino IDE 1.0.1 or later version. Because of the ATmega32U4 as its sole microcontroller, allows the RoMeo V2 to be simpler to use. Also,The 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol! The best advantage is that ATmega32u4 has two serial ports which allows you uploading sketches without removing wireless modules. Debuging is no longer a pain work.
Romeo V2 also improves the power supply, it has now a switch to select power source either from USB or external power.
Produce 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.
