Romeo family is an All-in-One Robot control board especially designed for robotics applications from DFRobot. It benefits from the Arduino open source platform, it is supported by thousands of open source codes, and can easily be expanded with your Arduino shields. The integrated 2 way DC motor driver and wireless socket allows you to start your own robot project immediately without the need for an additional motor driver. Not just has the motor driver, Romeo is also designed to have extra power for servos which need more current.
Romeo is also featured with DFRobot's standard 3 Pin-out designed and compatible with Gravity series sensors and actuators. Hundreds of sensors are now plug-play with Romeo.
