Before you start

Applying Power

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, Please select “Arduino UNO” as the hardware.

Romeo Configuration

Servo Power Select Jumper

As most servos draw more current than the USB power source can supply. A separate servo power terminal is provided to power the servo individually. This option can be Enabled/Disabled by the Servo Power Select Jumper.

When the Servo Power Select Jumper is applied, the servo is powered by internal 5V.

When the Servo Power Select Jumper is not applied, the servo is powered by external power source.

The Romeo V1.0 uses an automatic switcher for the power source selection. When the external power source has been applied, the servo will be automatically powered by the external power instead of USB power.

Motor Control Pin Jumper

Applying the Motor Control Pin Jumpers will allocate Pin 5,6,7,8 for motor control.

Removing the jumpers will release the above Pins, and the motor controller will be disabled.
