Introduction

The RoMeo BLE controller possesses all the functions of RoMeo controller, but adds one significant feature Bluetooth wireless communication, which allows the BLE controller to receive commands via Bluetooth. This offers the BLE a dazzling degree of customization in addition to new capabilities users can now use their smartphone, tablet, or computer to interact with the BLE. This grants users exciting new possibilities, such as being able to fully control their mobile platforms straight from their smartphone.

Paired with Arduino, the BLE offers a dynamic range of possibilities compared to previous Arduino controllers. The RoMeo BLE is a control board specially designed for robot applications. Owing to Arduino's open-source platform and publicly available open-sourced codes, the BLE is easily integrated with Arduino modules.

The RoMeo BLE also includes two integrated two-channel DC motor drivers and wireless sockets, which provides a simpler and more convenient way for users to get their projects started.

Pin Description

Figure 1 Romeo BLE Pin Out

More detail:
• Motor Control Terminal Jumpers Enable motor control if connected
• Button S1 to S5 Switch Enable button functions if switched "ON" in this case, all buttons are
connected to A7 .

Cautions Please turn OFF the Motor Power Switch, when you debug the motor with USB port.

Before you start

Applying Power

Power from USB Plug in the USB cable to the RoMeo controller from a power source i.e. wall jack or computer . Your RoMeo should turn on -- if it does, you should notice the LED light up. Please note that the USB can only supply 500 mA current, which is enough to light up the LED but insufficient in powering DC motors or servos.

Power from External Power Input Connect the ground wire usually the black 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".

Cautions Maximum supply voltage cannot exceed the voltage mentioned in Specifications.

Software

RoMeo can be programmed by Arduino IDE 0022 and above version. It can be downloaded at Please select “Arduino UNO” as the hardware.

Romeo Configuration

Servo Power Select Jumper

Since most servos draw more power than a USB power source can supply, a separate power source is needed to individually power the servo. That separate power source is usually packaged together with the servo When you connect the external power to the servo power supply, it will automatically select the power source either internal 5V power supply or external power source.

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.

New function

RoMeo BLE is an upgrade of RoMeo, based on which a new element - Bluetooth is added. It makes RoMeo BLE continue to obtain Bluetooth wireless communication ability after inheriting RoMeo's powerful motor drive ability. RoMeo BLE has stronger voltage and current capacity with voltage input range widened to 5-23V and current output capacity increased to 2A. Thus it can meet to more demands. Sheild interfaces are increased for I2C, IOREF and AREF, so as to compatible with more Sheild module. The buttons are replaced with comfortable and stable ones, and the jumper of buttons are also replaced with switch, making it easy to use.
