Arduino® UNO™ Q - Linux-capable dual-brain board
The Arduino® UNO™ Q extends the classic UNO platform with a powerful Linux processor. The board combines a Qualcomm® Dragonwing™ QRB2210 microprocessor with a real-time capable STM32U585 microcontroller.
This allows Linux applications and classic microcontroller tasks to be implemented in parallel on one board.
The UNO Q is suitable for classic Arduino projects as well as for applications in the fields of IoT, robotics and edge computing.
Two computing units, clearly separated
- Linux® Debian on the microprocessor - for Python applications, network services, data processing as well as image and audio applications
- Real-time MCU on the STM32U585 - For sensors, actuators and time-critical control tasks
Both units work independently but can communicate with each other.
Typical areas of application
- Prototyping for IoT and robotics applications
- Edge AI and local data processing
- Control tasks with simultaneous Linux application
- Teaching, training and research
Software & development
The Arduino App Lab is pre-installed on the UNO Q and serves as a central development environment.
It enables the combination of:
- Arduino sketches
- Python scripts under Linux®
- optional, container-based AI models
The Arduino IDE and the Arduino CLI can also be used.

FAQs - Arduino® UNO™ Q
What is the Arduino UNO Q?
The Arduino UNO Q is a Linux-capable development board from the UNO family. It combines a quad-core Qualcomm Dragonwing™ QRB2210 with GPU and an STM32U585 microcontroller. This allows Linux applications, real-time control and lightweight AI functions to be combined on a single platform.
Is the UNO Q open source?
Yes. The UNO Q schematics and Gerber files are available under the CC-BY-SA 4.0 license.
Which development environment do I need for Linux and Arduino applications?
The Arduino App Lab is already pre-installed on the UNO Q. Simply connect the board to your computer and load Arduino App Lab - without any complex configuration.
If you use the UNO Q as a single-board computer (SBC), a USB-C dongle with keyboard, mouse and monitor is all you need to get started right away.
Which operating systems are supported by Arduino App Lab?
Arduino App Lab runs on all common operating systems:
-
Windows 10 or newer (64-bit)
-
macOS 11 or newer (64-bit)
-
Ubuntu 22.04 or newer
-
Debian Trixie (64-bit)
In addition, Arduino App Lab is already installed natively on the Debian operating system of the UNO Q.
Can I continue to use the Arduino IDE?
Yes. You can use the Arduino IDE or the Arduino CLI as usual to run sketches on the microcontroller subsystem. However, to exploit the full potential of the UNO Q - including Python® and AI integration - we recommend using Arduino App Lab.
How do I connect a keyboard, mouse and monitor to the UNO Q?
Via a USB-C dongle with Power Delivery (PD) and video output. The dongle supplies the board with power and simultaneously provides connections for the display and USB peripherals. Important: The UNO Q will not start without Power Delivery. The 4 GB RAM version is recommended for stand-alone operation.
Can I develop wirelessly with the UNO Q?
Yes. Simply connect the UNO Q and Arduino App Lab via WLAN or Ethernet in the same network. Parallel development with several boards is also possible.
UNO R4 or UNO Q - which board is the right one?
-
UNO R4: Pure microcontroller board for energy-efficient real-time applications, sensors, actuators and classic IoT projects. Ideal for learning, prototyping and hardware-related developments.
-
UNO Q: Extension of the UNO concept with a Linux-capable processor. Ideal for AI applications, image and audio processing as well as complex web or edge applications - with simultaneous real-time hardware control via the STM32.
2 GB or 4 GB RAM - which variant should I choose?
-
2 GB: For cost-optimized, dedicated and lighter applications.
-
4 GB: For stand-alone operation, multitasking, demanding AI models, higher system reactivity and more local memory requirements.
Is Arduino App Lab open source?
Yes. Both Arduino App Lab and the App Bricks Library are open source. The corresponding source code repositories are publicly available.
