Arduino has introduced a new variant of its UNO Q board, significantly boosting its memory capacity with 4GB of RAM and 32GB of eMMC storage. This iteration is designed to meet the demands of developers working on advanced projects that require more robust processing power and storage, such as AI model deployment or multitasking applications.
The Arduino UNO Q, originally launched in early October 2025, combines a Qualcomm Dragonwing QRB2210 microprocessor with an STM32U585 microcontroller. The new 4GB variant builds on this foundation, offering greater versatility for tasks that benefit from additional memory, such as running complex AI models or managing multiple high-level processes simultaneously.
Developers who previously relied on the 2GB RAM version for efficiency can now opt for the 4GB model if they need to handle larger workloads. This includes scenarios like running a Linux desktop environment with a graphical user interface, processing high-resolution computer vision data, or logging extensive sensor data over long periods.
The 32GB eMMC storage provides ample space for development environments, project assets, and data logs, making it ideal for projects that require substantial built-in storage. While the original 2GB variant remains a capable choice for lightweight, single-process applications, the new 4GB model is better suited for more demanding tasks.
Arduino emphasizes that both variants maintain the same form factor and ease of use, ensuring compatibility with existing projects while unlocking new possibilities. The dual-brain architecture of the UNO Q continues to bridge high-performance computing with real-time control, making it a versatile tool for development, robotics, and edge computing.
Availability details indicate that the 4GB variant is currently available through authorized distributors such as RS Components, Farnell, DigiKey, Mouser, and Robu.in. Pricing starts at $10, reflecting its cost-efficient approach to advanced development needs.
