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 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.

| Features |
*A low-cost controller board designed for domestic Arduino fans. Full compatible with Arduino UNO R3.
*Suitable for Arduino Beginners.
|
*Low-cost mian controller board. The main difference from the official one is that this board offers XBee socket and SPI directly-plugged interface, making the best of UART ports.
|
*DFRduino Mega 2560 comes with plenty of IO ports, 54 digital ports, 16 analog ports, and 4 UARTs.
*Applicable to large projects that requires many sensors.
|
*Mega1280 has as many IO ports as Mega256, but comes with a smaller Flash. Besides, its price is lower than Mega2560.
*Suitable for low-cost projects requiring many sensors.
|
*Romeo V1 is specially designed for robot fans. It integrates motor driver, all sorts of communication ports, IO expansion port and so on.
*Extremely suitable for robot fans.
|
*The only difference between V1 and V2 is that Romeo V2 adopts ATmega32u4 chip, which provides 2 UARTs, convenient for wireless communication.
*For robot fans to build up projects with wireless communication.
|
*The first Arduino compatible controller board that integrates Bluetooth 4.0, bring much more flexibliy and possibility for Android and IOS mobile development.
*For Android and IOS mobile App BLE developers.
|
*Integrated CC3000 wifi core and SD card function. Can store a large number of collected data. Compared with Wifi shield, wido is more lightweight and low-cost.
*For IoT developers.
