The Arduino UNO Q (2GB) is a dual-processor UNO-format development board that combines a Debian-based Linux computer with a real-time STM32U585 microcontroller on a single board. The Linux side runs on a Qualcomm Dragonwing QRB2210 — a quad-core 2.0 GHz SoC with Adreno GPU and dual ISPs — making it capable of computer vision, audio processing, and running full Python environments. The STM32 side handles precise, deterministic tasks like motor control and sensor I/O, and the two processors work together seamlessly through Arduino App Lab.
What makes this board stand out is the combination of UNO-compatible form factor with serious compute power. You can plug in classic Arduino UNO shields, connect Qwiic/I2C modules via the onboard connector, and develop using both Arduino sketches and Python in one workspace. The board includes an 8×13 LED matrix for status feedback and supports Wi-Fi for wireless development and IoT connectivity.
For development, you can work directly on the board by connecting a USB-C hub with HDMI output (turning it into a mini desktop), or develop from a PC with wired or wireless OTA uploads. This makes it ideal for robotics (vision + motor control), edge AI (on-device inference with camera input), and IoT prototyping where you need both Linux flexibility and real-time microcontroller precision.
Compared to running a separate Raspberry Pi alongside an Arduino, the UNO Q integrates both into one board with a unified development environment — simpler wiring, less complexity, and a familiar UNO footprint.

Develop and scale faster with a powerful onboard CPU — the Qualcomm Dragonwing QRB2210 for AI vision and audio — paired with an STM32U585 microcontroller for precise, deterministic control. The UNO Q supports classic UNO shields, new carrier boards, and Modulino / Qwiic / PiicoDev modules for rapid prototyping.
Features and Applications
- Dual-processor architecture: A Debian-based CPU runs vision, audio, and user interfaces, while the real-time MCU manages precise timing, motor control, and sensor I/O.
- Simplified development: Use Arduino App Lab to write Arduino sketches and Python together in one workspace, with ready-to-run examples to accelerate projects.
- Fast MVP prototyping: UNO form factor with an onboard 8×13 LED matrix for status or UX feedback, plus a Qwiic connector for quick sensor and peripheral integration.
- Flexible workflows: Develop directly on the board using a USB-C hub or dock with HDMI output, or connect to a PC for wired or wireless OTA development.
- Robotics-ready: Leverage the CPU for computer vision and high-level logic while the STM32 microcontroller handles deterministic tasks like motor driving and sensor reading.
- Edge IoT and AI: Built-in Wi-Fi and peripheral support enable local data collection, on-device inference, and cloud connectivity for low-latency, offline-capable solutions.
- Powered by Qualcomm Dragonwing QRB2210: Quad-core 2.0 GHz SoC with Adreno GPU and dual ISPs, supporting cameras, displays, and audio for compact machine-vision and multimodal applications.
Jargon buster
Plain-language definitions for the technical terms used above.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- OTA
- OTA means over-the-air updating, where a device's firmware is updated wirelessly rather than through a programming cable. This lets firmware be updated or maintained after a device is installed without a physical connection.
- Qualcomm Dragonwing QRB2210
- A specific Qualcomm processor module aimed at embedded computing, camera, and edge AI applications. Knowing the exact processor helps you judge software support, performance, and whether the board can run Linux-based workloads.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- STM32
- STM32 is a family of microcontroller chips commonly used in embedded electronics. Knowing a product uses an STM32 can help when looking at firmware updates, pin connections, or low-level serial control options.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
