The Beetle BLE (formerly known as Bluno Beetle) is an ultra-compact miniature Arduino board based on the Arduino Uno with integrated Bluetooth 4.0 (BLE) functionality. This tiny powerhouse combines the familiar Arduino programming experience with wireless capabilities, making it perfect for DIY projects, educational purposes, and wearable electronics applications.
The development board can be programmed through its micro USB port using the standard Arduino IDE without any extra libraries or drivers, and it also supports wireless programming via Bluetooth. With its V-shaped gold-plated I/O interfaces, you can easily connect wires without soldering, making it especially useful for creating smart bracelets, clothing, and other wearable devices.
This versatile Bluetooth 4.0 microcontroller is fully compatible with Bluno series commands and procedures, supporting both Bluetooth HID and iBeacon modes. The Play Bluno app, available for both iOS and Android, gives you quick access to this tiny board for remote control and wireless program updates.
Despite its small size, the Beetle BLE packs impressive features including an ATmega328 microcontroller running at 16MHz, four digital pins, four analog pins, two PWM outputs, and both UART and I2C interfaces. For students and makers on a budget, this compact BLE development board offers an affordable solution for creating wireless projects without sacrificing functionality.
Whether you're building a smart device, working on an e-textile project, or teaching electronics, the Beetle BLE delivers big performance in a tiny package.
