Beetle BLE - Bluetooth 4.0

Description Beetle BLE

The Beetle Ble is a Arduino Uno-based board with Bluetooth 4.0 (BLE). It is probably the smallest Arduino BLE board on the market.
It uses standard Arduino IDE to upload codes via without additional library and drivers.
This Beetle BLE is another milestone in the Beetle line, giving do-it-yourself users more options in project design.
It is fully compatible with Bluno in instructions and procedures. Support Bluetooth HID and ibeacon modes.
You can also refer to the Bluetooth microcontroller selection guide for more information.

The Beetle BLE offers a super small and cheap Arduino with Bluetooth 4.0. The Beetle BLE can be used for disposable projects such as DIY projects, workshops, gift projects, wearable and educational e-textiles.
For students and makers who can't afford too much to buy hardware, the Beetle can be a great solution for them.

Just like a native Arduino board, but with Bluetooth 4.0. An APP called Play Bluno is available on IOS and Android that gives quick access to this tiny little board.

It not only supports USB programming, but also a wireless upload method. With the V-shaped gold plated I / O interface, it is convenient to screw conductor wire on it, which could be a good choice in the portable market.
