Arduino UNO Q – a hybrid board with Qualcomm QRB2210 and STM32U585

Description

The Arduino UNO Q development platform integrates the quad-core application microprocessor Qualcomm® QRB2210 and the low-power STM32U585 microcontroller, providing simultaneous execution of applications in the Linux environment and real-time control of devices. By combining microprocessor and microcontroller technologies, the board enables the creation of advanced systems in fields such as mobile robotics, image processing, sound analysis, IoT systems, and embedded AI applications.

The Qualcomm QRB2210, based on the ARM Cortex®-A53 architecture (4× 2.0 GHz), is supported by the Adreno™ graphics unit and AI accelerator, enabling the execution of complex computational and multimedia tasks. The STM32U585 microcontroller, based on the Cortex®-M33 core, operates under Zephyr OS and provides deterministic control of hardware peripherals. Both systems communicate through a dedicated IPC interface, enabling real-time data exchange.

The board features 2 GB of LPDDR4 RAM and 16 GB of eMMC memory, as well as communication interfaces including I²C/I3C, SPI, UART, CAN, GPIO, ADC, and PWM. It also offers a MIPI DSI connector for display connection, an audio output, and a microphone input. Wireless communication modules Wi-Fi 5 and Bluetooth 5.1 ensure connectivity in modern network applications.

The integrated Arduino App Lab environment allows the creation of applications using Arduino sketches, Python scripts, and AI models running in Docker containers. The Debian system with preinstalled App Lab enables work to begin without additional configuration. The board supports the Arduino UNO shield format and includes a Qwiic connector, making system expansion with additional modules possible without soldering.

Additional components, such as an 8×13 LED matrix, four RGB LEDs, a user button, and a USB-C port with video output and host/device functionality, allow for prototyping user interfaces and displaying data directly on a screen. The UNO Q is used in systems integrating classic microcontroller control with data processing under Linux, including edge devices, autonomous mobile platforms, interactive multimedia devices, and embedded systems with AI capabilities.

Compatibility with Arduino UNO projects

UNO Q maintains the physical Arduino UNO form factor and 5 V logic compatibility, allowing the use of existing shields and projects without hardware modification. Support for the classic Arduino IDE, Arduino CLI, and App Lab environment ensures full programming compatibility.

Performance and computing power

The quad-core Cortex-A53 processor running at 2.0 GHz provides the performance required for tasks such as image analysis, sound recognition, local AI model processing, and handling complex user interfaces. The STM32U585 microcontroller acts as a low-level controller, managing precise real-time operations.

Integrated containerization and multilingual application support

Docker and Docker Compose support allows running applications in isolated environments, simplifying testing and deployment of multi-component systems. App Lab integrates Arduino sketches, Python code, and AI models, streamlining the development of hybrid applications.

Expandability and solderless prototyping

The Qwiic connector enables quick connection of ready-made extension modules from SparkFun, Adafruit, or Pimoroni without soldering. The UNO form factor and interfaces I2C, SPI, UART, CAN, GPIO, and ADC allow integration with a wide range of sensors, actuators, and peripheral devices.

Modern communication and multimedia interfaces

The USB-C port allows data transfer, power supply, and video output, making it possible to create interactive user interfaces using external displays. Audio interfaces are also available — microphone input, line-out, and headphone output.
