Introduction

RoMeo V2[R3]is an All-in-One Arduino compatible microcontroller especially designed for robotics applications from DFRobot. The Romeo benefits from the Arduino open source platform, it is supported by thousands of open source codes, and can easily be expanded with Arduino Shields. The integrated 2 way DC motor driver and Xbee socket allows you to start your project immediatly without the need for an additional motor driver or wirless shield.

The analog sensor port pin mapping on RoMeo v2 is different from the version before. Be careful to wire your sensor or other devices correctly or the wrong power connection would destroy your device.

Please Turn OFF the Motor Power Switch when debugging Romeo through USB cable. Or the external power supply >12V will destroy your Romeo.

NOTE:
• Please select Leonardo board when uploading a sketch by Arduino IDE.
• Serial port 0 or 1 Read more from Arduino.cc Please use Serial1.*** instead of

Serial.*** in code to communicate with devices connected to serial interface, i.e. Pin e.g. Bluetooth, WiFi module, Xbee etc. Serial.*** is for USB debugging on pc serial monitor.
• Analog 0 If you are going to use the Analog port 0, you have to pay attention to the switch s1-s5 , turn it OFF please. There are five buttons connected to A0, if you turn ON the button switch,then the A0 read value would be not the one you want.
