DFRobot Bluno - An Arduino Bluetooth 4.0 (BLE) Board Micro Controller Board Electronic Hobby Kit

Bluno is a Bluetooth 4.0-enabled Arduino-compatible development board designed for fast and reliable wireless IoT projects. Combining an ATmega328 microcontroller with an onboard TI CC2540 BLE chip, it lets you send and receive data with smartphones, tablets, and PCs without dealing with complex Bluetooth protocols. Simply program it via the Arduino IDE and start building home automation, environmental monitoring, robotics, and smart control systems. Bluno supports wireless programming over BLE, Bluetooth HID, AT commands for easy BLE configuration, and transparent serial communication. It is fully compatible with Arduino Uno pin mapping, making it simple to migrate existing projects. Power it via USB or a 7–12 V DC supply. With rich I/O interfaces and support for a wide range of sensors and actuators, Bluno is ideal for rapid prototyping and education.
