Bluno - An Arduino Bluetooth 4.0 (BLE) Board
15 units available with a short lead time.
The Bluno integrates a TI CC2540 Bluetooth 4.0 (BLE) chip with an Arduino Uno-compatible development board, enabling wireless communication for your Arduino projects. It supports wireless programming via BLE, Bluetooth HID, AT command configuration, and transparent serial communication.
Fully compatible with all Arduino Uno pins, any existing Uno project can go wireless simply by switching to Bluno. DFRobot provides open-source apps for both Android and iOS to communicate with Bluno devices.
