Overview
The Arduino UNO Q 4GB is a groundbreaking development board for high‑performance edge AI and robotics, integrating the powerful Qualcomm® Dragonwing™ QRB2210 microprocessor with a real‑time STM32U585 microcontroller in the classic UNO form factor. Onboard 4GB LPDDR4 RAM and 32GB eMMC storage run native Linux Debian and Zephyr RTOS, creating a dual‑core brain that seamlessly combines high‑performance computing with precise real‑time control. With dual‑band Wi‑Fi 5, Bluetooth 5.1, full Arduino UNO shield compatibility, and Qwiic interface, it delivers a complete toolkit for next‑generation AI vision, audio, and IoT projects.

A Unique Hybrid Computing Architecture
At the heart of the UNO Q is its dual‑core design. The quad‑core Arm® Cortex®‑A53 MPU handles complex upper‑layer applications such as the Linux Debian OS, AI model inference, graphical interfaces, and network communications. Meanwhile, the Arm® Cortex®‑M33 MCU ensures hard real‑time performance for precision motor control, sensor reading, and immediate interrupt handling. Both work in concert, allowing developers to run data‑intensive computing and low‑latency control on a single hardware platform—eliminating the need for cumbersome communication between a single‑board computer like a Raspberry Pi and a traditional microcontroller.

Out‑of‑the‑Box Edge AI Capability
Thanks to the integrated Adreno GPU and dual ISP inside the MPU, the UNO Q is inherently equipped for AI acceleration. Deploy pre‑trained models using TensorFlow Lite or PyTorch to enable real‑time image recognition, object tracking, voice command recognition, and other AI applications. The onboard 8×13 programmable LED matrix provides quick visual feedback for AI inference results or system status, dramatically lowering the entry barrier and development cycle for edge AI projects.

Seamless Arduino Ecosystem Compatibility
Despite its performance leap, the UNO Q retains the classic UNO pin layout, granting direct access to thousands of existing Arduino shields. An onboard Qwiic connector supports solder‑free modular expansion, making it easy to connect Gravity‑series sensors, actuators, and Modulino modules. This means the vast Arduino open‑source library and community resources remain fully available, protecting your previous investments and enabling smooth project upgrades.

A Unified, Modern Development Experience
With the new Arduino App Lab, developers can use Python to write complex application logic running on Linux, and simultaneously use Arduino C/C++ to write real‑time control programs on the MCU—all within a single integrated environment. This hybrid programming approach significantly boosts development efficiency. Docker containerization is also supported, offering ultimate flexibility for advanced applications. The USB‑C port provides power, video output, and data transmission, allowing you to connect a display, keyboard, and mouse to turn the board into a complete micro‑desktop.
