Arduino UNO Q Technical Whitepaper: MPU·MCU Hybrid Board for Cloud-Free Edge AI
Published2026.10.09 23:31Arduino UNO Q is a product that integrates a Qualcomm Dragonwing QRB2210 microprocessor (MPU) running Debian Linux and an STM32U585 microcontroller (MCU) executing Arduino sketches on Zephyr RTOS into a single UNO form factor board. The two processors do not share RAM and resources, exchanging data only through remote procedure calls (RPC) of Arduino_RouterBridge, and the development environment Arduino App Lab and apps reside within the board. This whitepaper describes the design intent of this hybrid architecture, development workflow, hands-on verification results, and limitations in industrial application based on webinar presentation materials and technical Q&A.
