The Bluno Nano combines an Arduino Nano-compatible ATmega328 microcontroller with an integrated TI CC2540 Bluetooth 4.0 (BLE) module in a compact 53 × 19 mm form factor. It enables wireless communication, wireless programming, and Bluetooth HID functionality — ideal for BLE-enabled wearables and smart devices where space and weight are limited.
The board supports transparent serial communication over BLE, AT command configuration, and easy firmware upgrades. It is compatible with Arduino Uno pin mapping and works with Arduino Nano-compatible expansion shields. DFRobot provides open-source companion apps for both Android and iOS.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- Bootloader
- Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.
- HID
- Human Interface Device is a USB device class used for keyboards, mice, gamepads and similar controls. If a board supports HID over USB, it can act like an input device to a computer without needing a custom driver.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- TI CC2540
- A Texas Instruments Bluetooth Low Energy chip used to add wireless communication to embedded projects. In this kit it provides the BLE connection, so it affects how the controller can send readings to a phone or be configured wirelessly.
