Qualcomm announced an agreement to acquire Arduino on October 7, 2025, and later referred to the transaction as completed. The same day, Arduino introduced the UNO Q, a hybrid board that combines a Debian-based Linux computer with a separate real-time microcontroller. As of August 16, 2026, this is an established product and ownership change—not a brand-new announcement. For buyers, the important question is whether UNO Q’s extra Linux capability justifies its higher price and complexity compared with a conventional Arduino or a general-purpose Linux single-board computer.
What happened to Arduino?
Qualcomm Technologies announced an agreement to acquire Arduino on October 7, 2025. The purchase price was not disclosed in the cited official material. Qualcomm said the deal would combine its processors and artificial-intelligence technology with Arduino’s maker, education and open-source ecosystem, which Qualcomm described as having more than 33 million active users. That user figure is a company-provided claim, not an independently audited count.
Qualcomm later described the Arduino acquisition as closed during a December 2, 2025 investor conference (transcript). Arduino continues to operate under its own name, with its own documentation, store, community and open-source materials. The available announcements do not establish that every future Arduino policy, license or product will remain unchanged, so long-term governance questions are still reasonable.
The timeline
- October 7, 2025: Qualcomm announces the acquisition agreement and Arduino announces UNO Q.
- January 20, 2026: Arduino adds a 4GB RAM/32GB storage UNO Q configuration (announcement).
- March 9, 2026: Arduino announces the more powerful VENTUNO Q platform.
- June 26, 2026: Arduino announces UNO Q price increases effective July 6.
- August 16, 2026: UNO Q is an established product, while VENTUNO Q’s final availability and retail terms should still be checked on its official page.
Is Arduino UNO Q really a Linux computer?
Yes, but it is not simply a traditional Arduino Uno running Linux. UNO Q is a dual-processor board. Its Qualcomm Dragonwing QRB2210 is a quad-core 64-bit Arm Cortex-A53 application processor running at up to 2.0 GHz. It runs a Debian-based Linux environment and provides graphics, image-processing capability, networking and the resources needed for Python, containers and higher-level applications.

A separate STMicroelectronics STM32U585 Arm Cortex-M33 microcontroller runs the Arduino Core on Zephyr OS. That side handles GPIO, sensors, PWM, motors and other timing-sensitive work. Arduino’s Bridge/RPC system lets Linux applications and microcontroller sketches exchange commands and data.
The architecture matters because ordinary Linux is not a hard-real-time operating system. A motor-control loop or precisely timed sensor task belongs on the STM32, while computer vision, web services, Python code or an AI model can run on the QRB2210.

Three ways to use it
- Standalone: connect a monitor, keyboard and mouse through a suitable USB-C hub or dongle.
- PC-connected: develop from a computer with Arduino App Lab and related tools.
- Networked: administer and develop on the board remotely over a network.
Arduino’s product material describes the board environment as Debian-based. Do not interpret references to Ubuntu 22.04 or later and Debian Trixie in App Lab’s host requirements as proof that Ubuntu is UNO Q’s default board operating system. Ubuntu is associated more explicitly with the later VENTUNO Q platform.
Standalone use has a practical hardware requirement: Arduino says a USB-C hub or dongle must provide appropriate power delivery, and the board will not boot through an inadequately powered dongle. A display-capable hub, USB-C power supply and input devices can therefore add to the real cost beyond the board itself.

UNO Q versions and current announced prices
| Version | Memory and storage | Announced US price effective July 6, 2026 | Best fit |
|---|---|---|---|
| UNO Q 2GB | 2GB RAM, 16GB eMMC | $59, up from $44 | Dedicated embedded projects, sensor gateways and smaller applications |
| UNO Q 4GB | 4GB RAM, 32GB eMMC | $79, up from $59 | Standalone use, multitasking and larger local workloads |
Arduino attributed the July increase to sharply higher memory-component costs in its pricing notice. These are announced US prices; regional tax, shipping, stock and live store pricing can differ. The 4GB model is not merely a cosmetic upgrade: additional memory and storage make it the more sensible choice for a monitor-based Linux setup, while the 2GB model can be adequate when the board runs a fixed application.
How development works
Arduino App Lab is designed to bring Linux applications, Python, Arduino sketches, AI models and modular “Bricks” for functions such as vision, sound, storage and cloud integration into one workflow. The Arduino IDE and Arduino CLI remain relevant for the MCU side.
A sketch and a Linux application are not executing on the same processor or under the same operating system. A typical project might capture camera frames and run Python inference on Linux, then send a command through Bridge/RPC to an MCU sketch that generates a precise PWM signal for a motor.
UNO Q versus a traditional Arduino
Choose a conventional Arduino when the project mainly needs GPIO, sensors, motors, simple connectivity, low power consumption and predictable startup. Arduino positions the UNO R4 WiFi for conventional 5V projects, introductory electronics and smart-home work that does not need heavy processing.
UNO Q is justified when the same device must also run Linux software, Python, containers, a camera pipeline, a local service or an AI experiment. Its trade-off is higher cost, a more involved software stack, Linux boot time and the need to understand two processors instead of one.
UNO Q versus a Raspberry Pi-class Linux SBC
UNO Q can function as a small Linux computer, but it is not a universal Raspberry Pi replacement. A general-purpose Linux SBC is usually the more natural choice for desktop use, web browsing, media, server software, broad operating-system choice and the largest accessory and tutorial ecosystem.

UNO Q’s advantage is architectural: it puts an Arduino-compatible real-time MCU on the same compact board. That is valuable for robotics, instrumentation and edge devices where Linux handles high-level logic while the MCU maintains dependable timing. If real-time I/O is incidental and general computing is the main job, a conventional Linux SBC is likely the simpler purchase.
What is Arduino VENTUNO Q?
VENTUNO Q is a later, more ambitious platform announced on March 9, 2026. Qualcomm says its Dragonwing IQ8 series provides up to 40 dense TOPS of NPU AI performance. Arduino pairs that high-performance processor with an STM32H5 microcontroller for real-time actuation. Arduino and Canonical announced Ubuntu and Debian support for the main processor.
VENTUNO Q targets generative AI, advanced computer vision, robotics, offline models and ROS 2-oriented workflows. Those capabilities are vendor specifications and positioning statements, not independent performance benchmarks. The announcement discussed Q2 2026 availability, but final August 2026 pricing, memory configurations and shipping status should be confirmed on the Arduino announcement and product page before purchase.

Qualcomm gains a direct route to makers, educators and embedded developers who may eventually design products around Qualcomm silicon. Arduino gains access to a major chip company’s application processors, wireless technology and AI tooling. UNO Q is the clearest expression of that strategy: it adds Linux and edge computing without discarding the microcontroller workflow that made Arduino accessible.
Arduino says UNO Q schematics and software are open source, but that does not automatically mean every Qualcomm firmware component, binary driver or vendor SDK is open. Buyers who require fully auditable hardware and software should inspect the relevant repositories and licenses rather than treating “open source” as a blanket description of the entire platform.
The official material emphasizes continuity and acceleration, not a guarantee about every future cloud term, compatibility decision or community-governance policy. Those questions cannot be settled solely by the acquisition announcement.

Who should buy UNO Q?
- Buy it for a project that needs Linux applications or Python alongside deterministic sensor, motor or GPIO control.
- Choose the 4GB/32GB model for a standalone monitor-and-keyboard setup, multitasking or larger local AI workloads.
- Choose the 2GB/16GB model for a dedicated embedded application where memory and storage demands are modest.
- Choose a traditional Arduino for simple, low-power, real-time control or introductory electronics.
- Choose a general Linux SBC for desktop computing, broad software compatibility and a large accessory ecosystem.
- Consider VENTUNO Q only when heavier AI, robotics or computer vision justifies a newer and more complex platform.
Costs beyond the board
A standalone UNO Q setup may require a USB-C power-delivery hub or dongle, compatible power supply, display, keyboard, mouse and possibly a camera, sensors, shields or actuators. The advertised $59 or $79 board price therefore is not necessarily the complete project budget. For a simple sensor lesson, those extra costs and the dual-processor learning curve can outweigh the Linux capability.
Bottom line
Qualcomm’s Arduino acquisition was announced in October 2025 and subsequently described as completed. UNO Q is genuinely Linux-capable, but its defining feature is the combination of a Debian-based Qualcomm computer and a separate STM32 Arduino/Zephyr microcontroller. It is best understood as a hybrid edge-computing and real-time-control board—not as a normal Uno replacement or a universal Raspberry Pi substitute. The right choice depends on whether Linux and Arduino-grade deterministic I/O are both worth the added price and complexity.
