Board schematics and gerbers are openly licensed under CC-BY-SA 4.0 and the App Lab toolchain is open, which is the same open-design-and-open-toolchain pair that puts beagley-ai at 5. This ladder scores the openness of design files rather than of silicon - the top rung says so in its own terms - and every board in the category runs on proprietary silicon, so the QRB2210 firmware blobs are not a reason to place it lower. The toolchain half rests on published source rather than on a vendor claim: github.com/arduino/arduino-app-lab is public under GPL-3.0, 19MB of Go and TypeScript carrying the app, ui-packages and standalone-apps trees, and github.com/arduino/app-bricks-py is public under MPL-2.0. Arduino's FAQ is stale on this point: it still answers "Is UNO Q open source?" with schematics and gerbers only, and its App Lab answer still reads "we are working to publish corresponding source code repositories, they will become available soon". The public documentation is the 109-page UNO Q user manual for ABX00162-ABX00173, served from docs.arduino.cc as a plain PDF with no registration, alongside the schematics, pinout, CAD and STEP downloads. The board is on open sale: the FAQ names the channels - "UNO Q is available to order from the official Arduino Store, RS Components, Digikey, Mouser, Macfos" - and the store sells both SKUs at EUR59,90 and EUR82,90. Firmware blobs are still recorded as required, on the proprietary Dragonwing QRB2210 the board is built around, which is what every other part in this category records for the same fact; but the manual narrows what that covers, and the narrowing is worth recording - the Adreno 702 graphics stack is open, with "hardware-accelerated 3D graphics rendering through open-source Mesa drivers", freedreno for OpenGL and turnip for Vulkan, and video encode and decode reached through plain V4L2. What remains closed is the SoC boot chain, which Arduino publishes nothing of.

  "Yes, UNO Q schematics and gerbers are available under the CC-BY-SA 4.0 license"; and, of the toolchain, "Yes, App Lab and the App Bricks library are open source; we are working to publish corresponding source code repositories, they will become available soon". The same FAQ names the sales channels - "UNO Q is available to order from the official Arduino Store, RS Components, Digikey, Mouser, Macfos, and in the future from other Authorized Distributors and Resellers"

  The UNO Q user manual for SKU ABX00162-ABX00173, 109 pages, modified 12/08/2026, served without registration next to the schematics, pinout, CAD and STEP downloads on the same docs page. It is the source of the blob picture as well as the datasheet one - the board is built on the "Qualcomm Dragonwing QRB2210 - System-on-Chip (SoC)" running a vendor Debian image, and Arduino publishes no boot firmware for it, while section 8 records the graphics side as open - "The Adreno 702 GPU provides hardware-accelerated 3D graphics rendering through open-source Mesa drivers", freedreno for OpenGL and OpenGL ES, turnip for Vulkan, and video encode/decode through V4L2 GStreamer elements
