DFRobot DFR0305 Romeo BLE - Arduino Robot Control Board with Bluetooth 4.0

The 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, 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. 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 design and is compatible with Gravity series sensors and actuators. Hundreds of sensors are now plug-play with Romeo. You may also check the Bluetooth microcontroller selection guide to get more information.

The Romeo BLE is a new member of Romeo Family. This robot controller inherits all functions of the Romeo all-in-one controller. The Romeo BLE has integrated Bluetooth 4.0, to give the robot control board the power of easy set up. Thanks to the Bluetooth 4.0, the Romeo BLE supports wireless sketch uploading which means you do not need to plug in a cable to upload new code. Just add a USB Bluno Link adapter and the Romeo BLE is ready to be updated.

With Romeo BLE, all DFRobot's mobile platforms and robots can now be used with iOS devices by APP "GoBle". Also, the Romeo BLE supports Visual Programming APP (WhenDo).
