DFRobot 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 likely 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 DFRobot's Beetle product line, 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. It can be used for one-off projects such as DIY projects, workshops, gift projects, and wearable e-textiles. Therefore, it is the perfect board for students and makers. An app called Play Bluno is available on iOS and Android, providing quick access to the Beetle BLE via Bluetooth.
