Beetle BLE - The smallest Arduino Bluetooth 4.0 (BLE)

The Beetle BLE (Formerly known as Bluno Beetle) is an Arduino Uno based board with bluetooth 4.0 (BLE). It is probably the smallest Arduino BLE board in the market. You can use the Arduino IDE to upload code without the need of extra libraries or 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. Supports Bluetooth HID and ibeacon modes.

The Beetle BLE offers a super tiny and low cost Arduino with bluetooth 4.0. The Beetle BLE can be used for disposable projects, such as DIY projects, workshops, gift projects, E-Textiles wearable and educational. For students and makers who can not afford too much on hardware purchasing, Beetle can be a great solution for them.
