Romeo V2-All in one Controller

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 immediately without the need for an additional motor driver or wireless shield.

Another improvement of Romeo V2 is that it supports stepper motor control.

The RoMeo V2[R3] behaves like Arduino Leonardo based on the ATmega32u4 chip,You can program it directly from the Arduino IDE 1.0.1 or later version. Because the ATmega32U4 is a sole microcontroller, it allows the RoMeo V2 to be simpler to use. Also,The 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol! The best advantage is that ATmega32u4 has two serial ports which allows you uploading sketches without removing wireless modules. Debugging is no longer a pain work.

Romeo V2 also improves the power supply, it has now a switch to select power source either from USB or external power.

Warning:The analog sensor port pin mapping on RoMeo v2 is different from the old version. Please select Arduino Leonardo board when using Arduino IDE.

Improvement compared with Romeo v1.1:
Wide operating input voltage.
Directly support XBee and XBee form factor wi-fi,Bluetooth and RF modules.
ON/OFF switch to control the system power from external motor power.
3 Digital I/O extension(D14-D16).
S1-S5 switch replace jump cap.
Micro USB instead of A-B USB connector.
Analog sensor extension port: Orange for Signal,Red for Vcc,Black for GND.
