Description :

- The Romeo family is an All-in-One Arduino based control board designed for robotics applications from DFRobot
- It benefits from the Arduino open-source platform and is supported by thousands of open-source codes
-The integrated 2-way DC motor driver and wireless socket allows for immediate robot project start without the need for an additional motor driver
- Romeo is also designed to have extra power for servos which need more current
-The Romeo BLE is a new member of the Romeo family which has integrated Bluetooth 4.0
- The Bluetooth 4.0 allows for wireless sketch uploading, eliminating the need for a cable
- The Romeo BLE supports uploading sketches wirelessly through a USB Bluno Link adapter
- The Romeo BLE is compatible with DFRobot's mobile platforms and robots and can be controlled through the iOS app "GoBle"
- The Romeo BLE also supports Visual Programming APP (WhenDo)
-Others have praised the Romeo BLE as a huge step up from standard Arduino boards, citing the additional headers and motor hookups as making it easy to work with.
