Build Faster with the Uno R3 by Dfrduino Arduino Compatible
Uno R3 by Dfrduino Arduino Compatible DFRduino Uno R3 is a fully Arduino Uno compatible board for learning, prototyping, and general embedded projects.
It keeps the familiar Uno layout and adds DFRobot’s color-coded headers, which make sensor wiring easier to read at a glance.
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 R3 compatible: Easy match for many tutorials and shields
- ATmega328 in DIP package: Handy for replacement and custom work
- Color-coded headers: Faster wiring and easier port spotting
- USB and DC input: Simple power and programming options
- Good starter board: Strong fit for learning and general projects
- Gravity-ready: Easy plug-and-play wiring for fast setup
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.
