DFRobot Bluno - an Arduino Bluetooth 4.0 (BLE) Board DFRobot Bluno series is an Arduino-compatible Bluetooth 4.0(BLE) hardware solution designed by makers,and for makers. All Bluno products are Bluetooth 4.0 ready,and enjoy features such as wireless programming,smart App controlling,long communication range,and plentiful periphery modules. Bluno is first of its kind in combing Arduino Uno with Bluetooth 4.0 (BLE), making it an ideal prototyping platform for both software and hardware developers to go low energy bluetooth Through the low-power Bluetooth 4.0 technology, real-time low energy communication can be made really easy Bluno integrates a TI CC2540 BT 4.0 chip with the Arduino UNO development board Bluno is also compatible with all Arduino Uno pins which means any project made with Uno can directly go wireless
