Arduino UNO Q Merges MCU Control with Qualcomm SoC for AI Edge Computing

Arduino UNO Q development board

The Arduino UNO development board remains a key platform in electronics prototyping and education. Known for its straightforward design and hardware flexibility, it enables hobbyists, students, and engineers to create a wide range of electronic systems — from simple LED circuits to advanced IoT and automation projects. Its open-source hardware ecosystem, broad peripheral support, and compatibility with various shields make it one of the most adaptable tools for embedded development.

In October 2025, Arduino expanded this legacy with the introduction of the Arduino UNO Q, a hybrid development board that combines microcontroller-level control with microprocessor-grade computing. The board integrates a Qualcomm QRB2210 SoC for Linux-based AI and edge computing tasks alongside an STMicroelectronics STM32U585 MCU for real-time processing. This dual-core architecture bridges low-latency hardware control and high-performance data processing, positioning the UNO Q as a next-generation platform for intelligent embedded systems.

In March 2025, Arduino expanded its lineup with the launch of India-made boards — Arduino UNO R4 WiFi and Arduino UNO R4 Minima. We’ve also covered related models, including the Arduino UNO R4, UNO R4 Minima, UNO R4 WiFi, and UNO Mini. You can check out those articles if you’re interested in exploring these boards further.

Arduino UNO Q’s main components

The Arduino UNO Q works seamlessly with Arduino App Lab, a visual development platform designed to simplify the creation of embedded AI applications. It allows developers to build intelligent systems by combining prebuilt functional modules, known as Bricks, with custom AI models for quick and intuitive prototyping. In addition to App Lab, the board supports Arduino IDE for traditional C++ sketches and Python, giving developers the flexibility to choose their preferred programming workflow.

Staying true to Arduino’s open-source philosophy, the Arduino UNO Q design files and Gerber layouts are released under the CC-BY-SA 4.0 license. The board is priced at $44 USD internationally, €47.60 in Europe, and around ₹4,699 in India. It is currently available for pre-order on the official Arduino Store, with shipments expected to begin soon through distributors such as RS Components, DigiKey, Mouser, and Robu (India), which lists tentative delivery starting October 24, 2025. More technical and purchase details can be found on the official product page and press release.
