Arduino has just dropped something exciting for makers, educators, and rapid prototypers alike — Modulino®, a brand-new family of compact, modular boards designed to revolutionize how we build and iterate electronic projects.
Whether you're working on a weekend hobby project or developing scalable prototypes, Modulinos open up a new world of plug-and-play creativity — allowing you to build smarter, faster, and with less complexity.
A Modulino® is a small, self-contained module that easily connects to your Arduino board via the Qwiic connector, using the I2C (Wire) protocol for communication. Each module comes pre-configured with a unique I2C address, though you can tweak this to your needs by referring to the official utilities section.
These modules are designed to snap right into your workflow, offering ready-to-use functionality out of the box, so you can focus on what matters most: bringing your ideas to life.
Seamless Integration, Minimal Effort
Here’s what makes Modulino special:
-
Modular and stackable design
-
Pre-assigned I2C addresses (configurable)
-
Quick plug-in via Qwiic connector
-
Cross-compatible with most Arduino boards
-
Backed by official Arduino Modulino libraries and GitHub support
Meet the Modulino Lineup
Here’s a breakdown of the initial Modulino offerings:
ModulinoButtons
The ModulinoButtons module is your go-to solution for adding user input in the form of tactile feedback. It features three physical buttons, each paired with an individually controlled LED. This lets you not only read button states (pressed or not) but also provide intuitive visual cues, such as status indicators, button activation, or guided input sequences.
Whether you’re creating custom controllers, game inputs, or user interfaces for IoT projects, ModulinoButtons makes it easy to design interactive systems without the need for complex wiring or code.
ModulinoBuzzer
With ModulinoBuzzer, you can give your project a voice. This compact module allows you to generate audio signals, from simple beeps and alerts to more complex sound patterns. You can control both the frequency and duration of the tone, making it perfect for notification systems, alarms, or even basic musical feedback.
It’s a plug-and-play sound module that adds a whole new sensory layer to your electronics.
ModulinoPixels
Want to add vibrant, dynamic lighting to your project? ModulinoPixels comes equipped with an array of 8 RGB LEDs, each individually addressable for custom colors and brightness levels. You can create anything from animated effects and color indicators to fully reactive visual feedback.
It’s ideal for wearables, dashboards, status bars, or any project that needs a splash of programmable color. You can even clear individual LEDs or reset the entire array in one command — giving you complete control over your light show.
🎚️ ModulinoKnob
The ModulinoKnob brings a familiar, intuitive control method to your designs. It includes a rotary encoder that can detect turns and direction, as well as a push-button for an extra layer of interaction. This makes it ideal for scrolling through menus, adjusting values, or navigating user interfaces — much like a volume dial or selection wheel.
Whether you’re building a media controller, synthesizer, or smart device interface, ModulinoKnob gives users a tactile, analog-style control experience.
ModulinoMovement
ModulinoMovement puts motion detection in the palm of your hand. It features the LSM6DSOX IMU sensor, which captures 3-axis acceleration data — enabling your project to detect movement, orientation changes, shakes, and even gestures. This module is great for motion-sensitive applications like fitness trackers, interactive toys, gesture-based controls, or smart robotics.
With seamless integration and robust performance, ModulinoMovement makes sensing motion simple and precise.
ModulinoThermo
Get precise environmental data with ModulinoThermo. Using the HS300x sensor, this module measures both temperature and humidity — giving you real-time climate readings in a small, efficient package. Whether you're building a weather station, monitoring greenhouse conditions, or creating an indoor comfort sensor, ModulinoThermo provides reliable and accurate data.
Its I2C interface ensures easy integration with your Arduino projects, while its compact form factor makes it suitable for space-constrained applications.
ModulinoDistance
Add spatial awareness to your projects with ModulinoDistance. Powered by a Time-of-Flight (ToF) sensor, this module can measure distance with high accuracy, making it perfect for detecting obstacles, managing proximity, or automating movement. Unlike traditional IR sensors, ToF offers more precise and consistent readings, regardless of ambient light.
It’s ideal for robotics, automated systems, smart entrances, or any project that benefits from accurate distance sensing — all with plug-and-play simplicity.
Plug & Code
Arduino provides a rich set of tools to get you started quickly. With the official Modulino libraries, integrating these modules into your sketches is as simple as a few lines of code. Everything is well-documented in the Modulino Library Docs, and the GitHub repo includes example code to get you rolling.
Modulino isn't just a product; it's a philosophy — a shift toward accessible, modular, and rapid prototyping. Whether you're building a custom interface, experimenting with environmental sensors, or bringing motion to life, Modulinos provide a reliable, easy-to-use foundation to get your ideas off the ground.
With Modulino, Arduino has once again lowered the barrier between inspiration and creation. So go ahead — mix, match, and build something amazing.
