DFRobot Romeo V2 Robot Control Board with Motor Driver

The Romeo V2 is a robot control board with motor drivers, the board is compatible with Arduino and has been designed for robotics applications. Romeo V2 benefits from the Arduino open-source platform and can be easily extended with Arduino-compatible shields. It has an integrated 2-way DC motor driver and an Xbee socket, which makes an additional motor driver or a wireless shield unnecessary. Romeo V2 also supports the control of stepper motors and behaves like an Arduino Leonardo, which is based on the ATmega32u4 chip. This allows for easy programming and debugging as well as the emulation of a computer keyboard, mouse, and more through the USB-HID protocol.

Features:
