Before you start
Applying Power
This is one of the most important steps in getting the Romeo up and communicating with your host
controller. You MUST make sure that you apply power to the Power Terminal using the correct polarity.
Reverse Polarity will damage the Romeo. We are not responsible for such damage, nor do we warranty
against such damage. Make sure you take time to apply power correctly. Otherwise, it could get costly for
you!
Power from USB: Simply plug USB cable, and the Romeo is able to work. Please notice that the USB can
only supply 500 mA current. It should be able to meet the most requirements for LED lit application.
However it is not enough to power DC motors or servo.
Power from Motor Power Input: Simply connect the ground wire from your supply to the screw terminal
labeled "GND", and then connect the positive wire from your supply to the screw terminal labeled "VIN".
NOTE: Maximum supply voltage cannot exceed 14V DC.
Software
RoMeo can be programmed by Arduino IDE 0022 and above. It can be downloaded at Arduino.cc
(http://arduino.cc/en/Main/Software), Please select "Arduino UNO" as the hardware.
