Awesome Extras

Romeo V2 - a Robot Control Board with Motor Driver (Compatible with Arduino), it is especially designed for robotics applications and extended devices. Romeo benefits from the Arduino open-source platform, it is supported by thousands of open source projects, and can easily be expanded with Arduino compatible Shields. 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.
Romeo V2 - a Robot Control Board with Motor Driver (Compatible with Arduino) 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 it's the sole microcontroller, Romeo V2 is simple and easy to use. The 32U4 chipset handles the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the very interesting USB-HID protocol! The best advantage is that ATmega32u4 has two serial ports that allow uploading sketches without removing wireless modules. Debugging is no longer a painful task.
Version History
  • Romeo V2 also improves the power supply, it has now a switch to select power source either from USB or external power.
  • Romeo V2.2 redesigns the power supply system to improve the stability of the ADC circuit.
