Build Faster with the Bluno Beetle (Arduino Compatible)
Bluno Beetle (Arduino Compatible) Bluno Beetle packs Arduino-compatible control and Bluetooth 4.0 into a very small board. It is a strong fit for wearables, tiny robots, compact sensors, and space-limited prototypes.
It keeps the easy Arduino workflow while adding BLE features like wireless data transfer, HID support, iBeacon support, and wireless programming through the Bluno ecosystem.
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
- Ultra-compact size: Easy to fit into wearables and small enclosures
- Bluetooth 4.0 built in: Add BLE without a separate module
- Arduino-compatible ATmega328P: Simple to use with familiar tools and code
- Wireless programming support: Update firmware without plugging in every time
- HID and iBeacon support: Good for creative interactive projects
- Micro USB onboard: Fast setup and charging-friendly wiring
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.
