You'll be notified about news and stock updates for this project.

ROBO UNO+ is a dev board compatible with the classic Arduino UNO R3, but with additional hardware features that make it a more comprehensive and versatile platform for enthusiasts and educators. The design of ROBO UNO+ grew out of the feedback from five years of workshops we have given to educators and students. To show off these new features, we’ve developed over a dozen projects that are ready to run on ROBO UNO+, including a perfect egg timer, a burglar alarm, and a traffic light.

With ROBO UNO+, the possibilities are endless. Whether you’re a beginner taking your first steps into the world of Arduino or an experienced maker pushing the boundaries of embedded systems, our board will empower you to bring your ideas to life in exciting and innovative ways. Welcome to the future of Arduino development!

Bells & Whistles

ROBO UNO+ is the Ultimate Arduino Uno-compatible board for makers, enthusiasts, and educators. In the dynamic world of electronics and embedded systems, the Arduino Uno has long been a go-to development board for both beginners and experts alike - it is simple, versatile, and has extensive community support. However, there’s always room for improvement! Integrating valuable feedback from five years of workshops and project development in our lab, we designed ROBO UNO+ from scratch as our contribution back to the community. Below are some of the improvements we’ve made.

USB Type-C Connector

Our feature list begins with the eagerly anticipated USB Type-C connector! With a USB Type-C interface, ROBO UNO+ not only aligns itself with the latest industry standards but also ensures seamless compatibility with a wide range of devices and accessories. Whether you’re programming the board, transferring data, or supplying power, the USB Type-C interface on ROBO UNO+ offers a more streamlined and convenient user experience.

Informative Labeling

Since this is a classic educational platform, we labeled all of the main components on the silkscreen so students can easily recognise and understand the board layout.

Buzzer, LEDs, Buttons

Audio feedback, ranging from simple alarms to musical compositions, is useful in many applications, so ROBO UNO+ includes a buzzer that is easy to program.

As for visual feedback, we incorporated three Neopixel RGB LEDs into ROBO UNO+. These programmable LEDs enable vibrant and eye-catching lighting effects, adding a touch of interactivity and creativity to your projects.

To further augment user interaction, ROBO UNO+ integrates four tactile buttons. These buttons can trigger specific actions or serve as input devices for controlling various functions in your projects. Whether you’re building a gaming console or an interactive installation, the buttons on ROBO UNO+ will provide an intuitive and engaging user experience.

A World of Expansion Boards

ROBO UNO+ boasts double header pin rows, providing increased connectivity options for additional sensors, actuators, and expansion modules. In addition to being compatible with the usual ecosystem of Arduino shields, ROBO UNO+ has a STEMMA QT / Qwiic JST connector that opens up an entirely new set of expansion boards for your projects.

OLED Display Port

ROBO UNO+ includes a standard four-pin connector for the popular SSD1306 OLED display. This plug-and-play feature allows for seamless integration the 128 x 32 pixel (0.91") display, providing a visual interface to showcase project data, status, user interactions, or even mini games.

Open Source

The schematics and 20 full project examples for ROBO UNO+ are all availabe in our GitHub repository.
