Introduction
Romeo is an All-in-One Arduino compatible microcontroller 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-compatible shields. The integrated 2 way DC motor driver and wireless socket allows you to start your project immediately without the need for an additional motor driver.
This Romeo BLE controller inherits all functions of Romeo all-in-one controller, on the basis of which it integrates Bluetooth 4.0 wireless communication function. You can describe it as a control board specially designed for robot applications, carrying the gene of Bluetooth 4.0 and being compatible with Arduino.
With Romeo BLE, all DFRobot’s mobile platforms and robots can now be played with iOS devices with the newest app “GoBle”. Enjoy!
