Explore the latest: Arduino’s growing open source ecosystem

The Arduino GitHub has been busy. Over the past few weeks, we’ve published and updated dozens of repositories spanning libraries, cores, and development tools, and we want you to explore them.

Whether you’re working with our newest hardware, building with the Arduino IDE, or diving into platform development, there’s something new for you to discover, contribute to, and build upon. This is open source in action: transparent, collaborative, and continuously evolving with the community.

Here is what’s new:

Fresh updates across the ecosystem

We’ve been expanding our open source presence across multiple product lines and platforms:

New hardware support

• Arduino Nesso N1 repositories: Libraries and examples for our newest IoT development board
• Modulino system: Modular sensor libraries for the latest Arduino Modulino® nodes
  – Arduino_Modulino: https://github.com/arduino-libraries/Modulino 
  – ArduinoGraphics: http://github.com/arduino-libraries/ArduinoGraphics 
  – Arduino_HS300x: http://github.com/arduino-libraries/Arduino_HS300x 
  – Arduino_LPS22HB: http://github.com/arduino-libraries/Arduino_LPS22HB 
  – Arduino_LSM6DSOX: https://github.com/arduino-libraries/Arduino_LSM6DSOX

  – STM32duino VL53L4ED: https://github.com/stm32duino/VL53L4ED

Development tools

• Arduino IDE: Fresh release with improvements and bug fixes published recently
• Arduino CLI: Latest updates to our command-line interface

Platform expansion

• MicroPython ecosystem: Growing support and libraries for MicroPython on Arduino boards
• Core libraries: Continuous improvements across AVR, SAMD, and other platforms

Each repository represents real work from both Arduino engineers and community contributors. Each one is an invitation to learn, improve, and collaborate.

Among new releases: Arduino UNO Q’s full stack

Among these recent additions, you’ll notice something interesting: a complete collection of repositories dedicated to the Arduino UNO Q, our Linux-powered board bringing Qualcomm Technologies’ AI capabilities to Arduino.

These aren’t just libraries, they’re the entire software ecosystem that makes Arduino UNO Q possible, from App Lab development down to the Linux kernel itself.

For each component, you can browse the source code, see what issues are being worked on, report bugs you find, or suggest new features. It’s all there, organized and accessible. 

• Arduino App Lab  
• Access Arduino CLI
• Access preinstalled Bricks
• Access all App Lab components

Open source is love

As we shared in our 2024 Open Source Report, open source is at the heart of everything we do. It’s not just a development model, it’s our commitment to transparency, collaboration, and shared innovation.

Collaborative by design. 

Open source enables real-time collaboration through pull requests, issue tracking, and community discussions. Your contributions become part of the platform millions use, and your feedback shapes Arduino’s future.

Real impact through collaboration. 

Last year, we contributed about 200 patches to the Zephyr codebase and released the first Arduino core based on Zephyr, a major milestone made possible only through open collaboration with the broader embedded systems community.

From our very first board in 2005, Arduino has been built on the principle that technology should be accessible to everyone. Open source isn’t just how we work, it’s who we are.

So dive in. Browse the repositories. Try something new. Every contribution, no matter how small, moves Arduino forward and we can’t wait to see what you create!

Your contributions shape Arduino

This ecosystem exists because of thousands of contributors worldwide who believe in open innovation. Whether you’re a developer, educator, student, or maker, there’s a place for you:

• Contribute code: Submit pull requests, fix bugs, add features.
• Report issues: Help us improve by sharing what you find. By the way, the Arduino App Lab repository has an issue tracker that can be used to submit formal bug reports and feature requests.
• Share knowledge: Answer questions, write tutorials, create examples.
• Build projects: Use and showcase what Arduino makes possible.
