Arduino UNO Q Development Board (4GB LPDDR4, 32GB eMMC)

The Arduino UNO Q (4GB LPDDR4, 32GB eMMC) is a dual-brain development board combining a Qualcomm Linux microprocessor with an STM32 real-time microcontroller. It offers single-board computer processing alongside deterministic hardware control in the classic UNO footprint. It is ideal for students, hobbyists, and engineers working on edge AI, computer vision, and autonomous robotics projects.

Dual-brain hybrid architecture

The Qualcomm Dragonwing QRB2210 quad-core MPU runs Debian Linux to handle networking, high-level logic, and media processing. Concurrently, the STM32U585 microcontroller executes real-time timing and motor control routines without interruption from operating system background tasks.

On-device AI and computer vision

Equipped with an Adreno GPU, dual ISPs, and 4GB of LPDDR4 RAM, the board accelerates local machine learning workflows. It supports real-time video stream processing for tasks such as object detection and gesture recognition directly on the device.

Unified software and container support

Developers can write standard Arduino sketches for the MCU, deploy Python scripts to the Linux MPU, or integrate both via the Arduino App Lab. The pre-installed Debian environment also includes Docker and Docker Compose support for containerised applications.

Modern connectivity and classic expansion

The board features dual-band Wi-Fi 5, Bluetooth 5.1, and a USB-C port that supports power delivery, host/device switching, and video output. Hardware expansion is provided via standard UNO shield headers, high-speed interface pins, and a solderless 3.3V Qwiic connector.

Built-in storage and visual feedback

With 32GB of onboard eMMC memory, the board boots and runs operating systems without requiring an external micro SD card. For status monitoring and diagnostics, it integrates an 8x13 blue LED matrix and four user-programmable RGB LEDs.
