Overview
Arduino UNO Q is a hybrid single-board platform that fuses a Debian Linux application processor with a real-time microcontroller — giving you the performance of a small computer and the timing accuracy of an MCU on one UNO-form-factor board.
At its core, UNO Q pairs a quad-core Qualcomm® Dragonwing™ QRB2210 (Arm® Cortex®-A53, 2.0 GHz) with an STM32U585 (Arm® Cortex®-M33, up to 160 MHz). Linux apps and Arduino sketches communicate over Arduino Bridge (RPC), so you can run high-level AI/vision or web services on Linux while the MCU handles deterministic control for motors, sensors, and I/O.
Key Features & Benefits
- Dual-core architecture: Combines a Linux-capable Qualcomm® Dragonwing™ processor with a real-time STM32U585 microcontroller for ultimate flexibility.
- AI & Vision Ready: Built-in Adreno 702 GPU, dual ISPs, and MIPI-CSI/DSI interfaces for cameras and displays — ideal for edge AI and machine vision projects.
- Seamless Development: Arduino App Lab lets you run Linux apps, Arduino sketches, and AI Bricks together from one environment.
- Full Connectivity: Dual-band Wi-Fi® 5, Bluetooth® 5.1, and USB-C® with DisplayPort Alt-Mode.
- Expandable Ecosystem: Standard Arduino UNO headers, Qwiic connector, and carrier board compatibility.
- Robust Power Options: USB-C (5 V/3 A) or VIN (7–24 V) with built-in protection and smart power routing.
- Modern Learning Platform: Perfect for education, prototyping, robotics, home automation, and edge computing.
