Qualcomm announced an agreement to acquire Arduino on October 7, 2025, and introduced the Arduino UNO Q, a single-board computer that pairs a Debian Linux application processor with a separate Arduino microcontroller. The combination is the board’s defining feature: Linux can run higher-level applications, while the MCU handles timing-sensitive hardware control. Qualcomm later called Arduino “a Qualcomm company” in a March 9, 2026 release, so the announcement and later status should not be conflated.

What the Arduino UNO Q is—and what Qualcomm’s announcement means

The UNO Q is not simply a faster version of a traditional Arduino UNO. It combines two processors with different jobs: a Qualcomm Dragonwing QRB2210 application processor (MPU) running Debian Linux, and an STMicroelectronics STM32U585 microcontroller (MCU) running Arduino sketches on Zephyr OS. That lets a project use Linux software alongside a dedicated controller for real-time inputs and outputs. Arduino’s UNO Q product page and its hardware documentation describe the board and its components.

On October 7, 2025, Qualcomm said it had agreed to acquire Arduino; that wording describes an agreement, not a completed acquisition on that date. A Qualcomm release dated March 9, 2026 later referred to Arduino as “a Qualcomm company.” Qualcomm’s October 2025 announcement said the Arduino brand, tools, mission, and support for microcontrollers and microprocessors from multiple providers would continue. Arduino’s FAQ describes its platform as open-source and community-focused. Qualcomm’s October 2025 announcement and its March 2026 release provide the respective statements.

Qualcomm reported 33M+ active users in the Arduino community in its 2025 announcement. That is Qualcomm’s published figure, not an independently audited count or a current user tally.

UNO Q hardware: two processors, two kinds of work

Component What it does Published specifications
Qualcomm Dragonwing QRB2210 MPU Runs Debian Linux and application-level software. Quad-core Arm Cortex-A53 at up to 2.0 GHz, Adreno GPU, and dual image signal processors. Arduino’s hardware documentation lists image processing at 13 MP + 13 MP or 25 MP at 30 fps.
STMicroelectronics STM32U585 MCU Runs Arduino sketches on Zephyr OS for control tasks. Arm Cortex-M33 up to 160 MHz, 2 MB flash, and 786 kB SRAM.
Memory and storage Supports Linux applications and local data. Arduino presents 2 GB and 4 GB RAM variants; its product page describes 16 GB eMMC storage. Confirm the specific model and regional listing before purchase.

These are manufacturer-published specifications, not independent performance results. In practical terms, the MPU is suited to Linux applications such as Python software, while the MCU is intended for deterministic sensor and actuator control. The split can simplify a design that otherwise would need a Linux computer and a separate microcontroller, but software and I/O choices still depend on the project.

Connectivity, expansion, and software options

Arduino lists dual-band Wi-Fi 5, Bluetooth 5.1, USB-C, traditional UNO headers, a Qwiic connector, and high-speed connectors for carriers and peripherals. UNO Q schematics and Gerbers are released under the CC-BY-SA 4.0 license, according to Arduino’s hardware documentation.

Arduino App Lab brings sketches, Python, and AI models into one development environment. It is not the only way to program the board: Arduino also documents Arduino IDE and CLI workflows for MCU programming. Check the relevant software documentation for the task and workflow you intend to use; App Lab should not be treated as a prerequisite. Arduino App Lab information and Qualcomm’s developer resources describe the available software direction.

Arduino and Qualcomm promote embedded AI, vision, image classification, object detection, sound recognition, smart sensing, automation, and prototyping as potential applications. These are vendor-described use cases; the published material cited here does not establish independent test results for those workloads.

Standalone setup: power and peripherals to plan for

Arduino says UNO Q can work as a standalone single-board computer with an external display, keyboard, mouse, and other USB peripherals connected through a USB-C dongle. For that configuration, the dongle needs both Power Delivery (PD) and video output. Arduino’s US Store listing calls for a PD-compatible supply and recommends at least 15 W, with 5 V/3 A given as an example. The hardware documentation recommends the 4 GB variant for standalone use. Check the current documentation and the exact regional product listing before selecting accessories.

  • Choose a USB-C dongle or hub that supports PD and video output if you plan to connect a display and USB peripherals.
  • Use a PD-compatible supply meeting Arduino’s stated recommendation for the store listing; do not assume any USB-C charger or adapter will work.
  • Consider the 4 GB model for standalone SBC use, following Arduino’s hardware documentation recommendation.
  • Check the connector and compatibility requirements for each shield, Qwiic sensor, camera, display, or carrier before buying.

The necessary setup depends on whether the UNO Q will be headless or used with a display and desktop peripherals. Arduino’s US Store page gives the dongle and power details for its listing.

UNO Q versus UNO R4: choose by workload

Arduino characterizes UNO R4 as a microcontroller board for straightforward real-time hardware control, and UNO Q as the option for projects that need Linux, Python, AI models, or computer vision alongside MCU control. The useful distinction is the software and workload the project needs—not a claim that one board is universally faster or better.

Project need Better fit based on Arduino’s guidance Why
Real-time hardware control without a Linux application environment UNO R4 Arduino describes it as a pure microcontroller board for straightforward real-time control.
Linux applications, Python, AI models, or computer vision plus MCU control UNO Q It combines a Debian Linux MPU with a dedicated STM32 MCU.

Before choosing, also consider RAM and storage needs, power and setup complexity, required real-time I/O, and compatibility with existing shields and peripherals. Arduino also compares UNO Q with Raspberry Pi, emphasizing the integrated STM32 MCU, UNO form factor and shield ecosystem, eMMC, and App Lab. That is the vendor’s comparison, not a neutral benchmark: the reviewed official material does not provide a like-for-like performance test establishing that UNO Q is faster or better than a Raspberry Pi.

Availability and what to verify before buying

Arduino’s product page names the Arduino Store and distributors including RS Components, DigiKey, Mouser, and Macfos. The list does not establish current stock in every country. The US Store page displayed a $59 price for the 2 GB UNO Q during the cited research period; price and availability can change, so check the live regional listing and confirm which memory variant it covers. Arduino’s product page links its stated sales channels.

For a purchase decision, verify the selected RAM variant, included storage and accessories, local availability, power-supply requirements, and compatibility with the shields or peripherals you plan to reuse. Published specifications can establish what Arduino says the board includes; they do not replace checking a particular seller’s current listing.

Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
