Beetle Bluno BLE smallest Arduino with Bluetooth 4.0

The Beetle BLE by 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 for programming the microcontroller. The Beetle BLE board is another milestone in the Beetle product line from DFRobot, offering hobbyists and makers even more possibilities in project design. 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-time projects such as DIY projects, workshops, gift projects, wearable e-textiles. So, for students and makers, this is the perfect board. An app called Play Bluno is available on iOS and Android, which gives you quick access to the Beetle BLE via Bluetooth.
