Build Faster with the Bluno Bluetooth 4.0 Microcontroller Arduino Compatible
Bluno Bluetooth 4.0 Microcontroller Arduino Compatible Bluno combines an Arduino Uno compatible controller with built-in Bluetooth 4.0. It gives you a familiar board layout plus easy BLE links for apps, sensors, and wireless control.
It is a good choice when you want standard Uno-style wiring, shield support, and wireless programming in one board.
Important: Use the official DFRobot links below for wiring, sample code, downloads, and the latest setup notes for this SKU.
Why you'll love it
- Uno-compatible layout: Easy upgrade for many Arduino builds
- Bluetooth 4.0 onboard: No need for a separate BLE shield
- Wireless programming: Update code through the Bluno family
- HID support: Can act like a wireless keyboard or mouse in supported projects
- AT command control: Flexible BLE setup and serial use
- Transparent serial mode: Clean wireless data link for apps and modules
What you can build
This board is a good fit for learning, prototyping, robotics, and controller-based builds. Use it as the main brain for sensors, displays, wireless projects, and classroom or workshop demos.
Starter bundles
A solid starter setup includes a USB cable, breadboard, jumper wires, and a few DFRobot Gravity sensors or an LCD module for quick testing.
Recommended add-ons
Useful add-ons include sensors, displays, shields, breadboards, headers, and enclosures if you are building a complete prototype or classroom kit.

Pinout & usage notes
Verify serial levels, baud rate, and pin mapping in the official DFRobot guide before first power-up. If you are using Gravity connectors, align the plug correctly and avoid forcing the cable into the wrong header. Use a suitable external power source for motion parts when the controller alone cannot supply enough current.
