DFRobot Beetle BLE - The Smallest Board Based on Arduino Uno with Bluetooth 4.0 Category_Grove (Arduino)/Grove Radio/RF 1″ male headers is includedThe Beetle Ble (Former name as Bluno Beetle) is a board based on Arduino Uno with Bluetooth 4. 0 (BLE). It is probably the smallest BLE board in the market. It uses standard Arduino IDE to upload codes via without any extra libraries and drivers. This Beetle BLE is another milestone in the Beetle line, which makes DIY users have more options in the project design. It is fully compatible with Bluno in instructions and procedures.
