Romeo family is an All-in-One Arduino based control board especially designed for robotics applications from DFRobot.  It benefits from the Arduino open source platform and it is supported by thousands of open source codes.

The Romeo BLE has integrated bluetooth 4.0,  it is the first time to give a robot control board the power of easy set up.  Thanks to the bluetooth 4.0,  the Romeo BLE supports uploading sketch wireless which means you do not need to plug a cable to upload new code: just need a USB Bluno Link adapter.

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 3Pin-out designed and compatible with Gravity series sensors and actuators.
