Arduino says it remains committed to its open-source ethos. In a recap of its November 19, 2025 Ask Me Anything about the Arduino UNO Q, the company reported that Qualcomm’s Adam Benzion emphasized a “100% commitment” to maintaining that ethos. Arduino pointed to the UNO Q’s released Gerber files and its engineers’ upstream work on Zephyr RTOS as examples—but the recap is not a license-by-license audit of every board component or software layer.
What Arduino said about staying open source
Arduino’s November 28, 2025 recap says the question of whether the company would remain open source came up repeatedly during the AMA. It quotes Benzion, Qualcomm’s Director of Strategic Partnerships, as emphasizing that “there’s a 100% commitment to maintain Arduino’s open-source ethos.” This is Arduino’s account of the panel discussion; the recap does not attach the statement to a transcript timestamp.
To illustrate the commitment, Arduino cited the public release of UNO Q Gerber files shortly after launch, the board’s use of Zephyr RTOS, and Arduino engineers’ upstream contributions. Those examples show activity the company considers consistent with its ethos. They do not establish that every hardware design, firmware layer, software component, or future product is open source, nor does the recap specify licenses or independently verify repository coverage.
What the UNO Q AMA covered
Arduino says the session ran for 60 minutes and focused on the UNO Q, Arduino App Lab, accessible AI, and the company’s direction. The panel included Andrea Richetta, Arduino Principal Product Evangelist; Adam Benzion, Qualcomm Director of Strategic Partnerships; Rami Mouro, Qualcomm Senior Engineer and Developer Advocate; Louis Moreau, Head of Developer Relations at Edge Impulse; and Erwan Gouriou, Principal Software Engineer at STMicroelectronics.

Arduino published selected questions and answers rather than a full transcript, and points readers to the YouTube recording. The company says questions were collected from social media and forums, but its recap does not reproduce their original wording. The questions below therefore summarize the topics rather than quote individual community posts.
How Arduino describes UNO Q’s two computing sides
The recap presents UNO Q as a dual-brain architecture that bridges Linux and a microcontroller workflow. In response to a technical question, it reports that the onboard STM32 U5 MCU has 2 MB of flash, 786 kB of RAM, and more than 20 communication peripherals. These are figures reported by Arduino’s recap of Gouriou’s explanation, not independently checked specifications in the recap.

The AMA also gave affirmative responses to questions about ROS 1 and ROS 2, the MCU waking the CPU through power management, and command-line development with Yocto or Foundries. Arduino reported that the IDE would remain free. The recap provides no implementation steps, software versions, or compatibility caveats, so these short answers should not be treated as broad guarantees for every setup or workload.
Will Arduino keep working with multiple chip vendors?
Arduino says Benzion reaffirmed a multi-vendor approach, naming STMicroelectronics, Microchip, Renesas, and other partners. That describes the company’s stated direction during the AMA; it is not a promise about the silicon used in any particular future board.

Where UNO Q users can look for help
Arduino directs beginners and experienced developers to Project Hub, tutorials, and forums. Asked whether an official UNO Q curriculum was planned, the recap said the team was working on one. That was the reported status in November 2025, not confirmation that a curriculum is currently available.
