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 low power use and broad compatibility with modern phones and computers. It connects well to battery-powered and mobile devices, including Apple hardware, though it behaves differently from Bluetooth Classic and its serial-style profiles.
- 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.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- 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 single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- TI CC2540
- The TI CC2540 is a Texas Instruments system-on-chip that combines an 8051 microcontroller core with a Bluetooth Low Energy (BLE) radio, used to add short-range wireless communication to embedded projects. It lets a device connect to a phone or another BLE device to exchange data or be configured wirelessly.
