Beetle Bluno BLE smallest Arduino with Bluetooth 4.0

The Beetle BLE from DFRobot is an Arduino Uno-based board with Bluetooth 4.0 (BLE).  It is probably the smallest Arduino BLE board on the market.  The standard Arduino IDE software is used to program the microcontroller.  The Beetle BLE board is another milestone in DFRobot's Beetle product range, opening up even more possibilities for hobby electronics enthusiasts and makers. The board is fully compatible with Bluno boards. The Beetle BLE is a super small and affordable Arduino board with Bluetooth 4.0. The Beetle BLE can be used for one-off projects like DIY projects, workshops, gift projects, wearable e-textiles. So for students and makers this is the perfect board. An app named Play Bluno is available on IOS and Android, providing quick access to the Beetle BLE via Bluetooth.
