We’ve already seen lots of amazing projects based on Arduino UNO Q come up since its launch in early October - but we’re doubling down anyway! Today, we are launching a new Arduino UNO Q variant with 4 GB of RAM and 32 GB of eMMC storage, allowing all of you to dream bigger and go further, while still enjoying the same Arduino UNO Q form factor and ease of use.

4 good reasons to choose 4 GB In this 4 GB variant, Arduino UNO Q still leverages a unique combination of powerful Qualcomm Dragonwing QRB2210 microprocessor and real-time STM32U585 microcontroller, but can now better meet the needs of developers who require a more ample memory configuration.

Choosing between the variants comes down to your priorities: the 2 GB variant of Arduino UNO Q provides optimized efficiency, while the new 4 GB variant maximizes versatility.

While the first variant of Arduino UNO Q remains a capable and powerful board, there are four specific situations where you’ll want to opt for the new one:

1. This new version is recommended if you intend to use Arduino UNO Q as a standalone SBC (single-board computer) - connecting a monitor, keyboard, and mouse via the USB-C hub and running the Debian Linux OS on the board with a graphical user interface. To enjoy a responsive Linux desktop experience in this case, the 4 GB RAM provides a comfortable baseline.

2. In the same way, the extra 2 GB of RAM are crucial to prevent slowdowns and crashes if your application involves multiple, simultaneous high-level processes - e.g. running the Arduino App Lab on the board, hosting a local web server, managing database logging, and streaming camera input all at once. The 2 GB variant of Arduino UNO Q remains perfectly suitable if you need to run a single, dedicated, lightweight process on the MPU.

3. Choose the 4 GB / 32 GB variant if you plan to use larger, more complex AI or machine learning models - such as high-resolution computer vision or sophisticated audio processing. While the 2 GB variant is suitable for smaller, memory-optimized tinyML applications, "heftier" models require a larger memory footprint to load files and process input data efficiently.

4. If you want substantial built-in storage for logs and data, as well as a robust development environment, the 32 GB eMMC gives you all the space you need for numerous Linux packages, large project assets, or long-term sensor data logs.

**More options, more power to you! ** No matter which variant is best suited for your project, Arduino UNO Q is the starting point that can help you bring to life infinite ideas because its dual brain bridges high-performance computing with real-time control.

We designed it to take you "from blink to think" in no time! Also thanks to the new Arduino App Lab, a whole new, all-in-one developer environment where you can seamlessly combine Arduino sketches, Python scripts, and containerized AI models.
