Bluno - Arduino UNO compatible Bluetooth 4.0 (BLE) Board

This Arduino UNO compatible board with Bluetooth is perfect if you want to control your Arduino projects with your phone via Bluetooth. Bluno integrates a TI CC2540 BT 4.0 chip with the Arduino UNO development board. It allows wireless programming via BLE, supports Bluetooth HID, AT command for BLE configuration, and you can also easily update the BLE firmware. Bluno is also compatible with all Arduino Uno pins, which means that any project made with Uno can become wireless directly! You can use Bluno with all Bluetooth 4.0 compatible devices and create features such as wireless transmission, master and slave settings, wireless programming, and even building a Bluetooth HID connection with the PC between devices. DFRobot has developed an app for Bluno (both Android and IOS), which is completely open source.

Note on Compatibility: Bluno Family does not support BLE devices from other brands because the Bluetooth profile differs. More on this in the Wiki.
