Product description
The Arduino® UNO™ Q 4GB bridges high-performance computing with real-time control in the Arduino UNO form factor. It combines a Linux Debian-capable Qualcomm® Dragonwing™ QRB2210 microprocessor with an STM32U585 real-time MCU—built for projects that need Linux-level applications and deterministic control on the same hardware platform.
4GB variant: recommended for SBC mode and more advanced AI/ML workloads
This version includes 4GB LPDDR4 RAM and 32GB eMMC. The manufacturer recommends it if you intend to use the board in single-board computer (SBC) mode, run multiple simultaneous high-level processes, deploy larger/more complex AI or machine-learning models, or require substantial built-in storage for data/logs and a robust development environment.
Hybrid design: Linux application processing plus real-time control
The “dual-brain” approach combines a Linux compute domain on the QRB2210 with a low-power real-time MCU for time-critical control tasks. This is relevant for systems where sensing, local processing, deterministic control, and user interaction need to work together.
Compute foundation: QRB2210 with GPU and imaging features
The Dragonwing™ QRB2210 is specified with a quad-core Arm® Cortex®-A53 @ 2.0 GHz, an Adreno GPU, and 2× ISP. This targets embedded vision, audio processing, and AI-adjacent workloads beyond classic microcontroller-only solutions.
Arduino ecosystem: shields, high-speed headers, and Qwiic
The board remains compatible with the Arduino UNO ecosystem via classic UNO headers for shields, adds high-speed headers for vision/audio/display peripherals, and includes a Qwiic connector (3V3, I2C) for Modulino® nodes and compatible I2C modules.
Arduino App Lab: unified development across Linux and real-time
Arduino App Lab is described as a unified development environment combining Arduino Sketches, Python® scripts, and containerized AI models into integrated applications managed from a single interface.
Interfaces, audio/video, and prototyping features
The listed interfaces include I2C/I3C, SPI, PWM, CAN, UART, PSSI, GPIO, JTAG, and ADC. Video output is supported via USB-C, with MIPI DSI pins on the JMEDIA header. Audio is provided via microphone in / headphone out / line out on JMISC. For user feedback and UI, the board includes an 8×13 LED matrix and RGB LEDs.
