RB-Dfr-582
DFRobot Romeo BLE All-in-one Microcontroller (ATMega 328)
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-comaptible shields.
The integrated 2 way DC motor driver and wireless socket allows you to start your project immediatly
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.
