Arduino USB Camera adds 4K capture and autofocus to Q-board designs

Arduino's USB camera combines MJPEG capture, autofocus, ring lighting and USB audio, but host power, decoding and hub requirements shape the design-in decision.

TL;DR — three sentences

  • The Arduino USB Camera supports up to 3840 × 2160 at 30 fps in MJPEG, while YUY2 uses lower resolution and frame-rate combinations. (S1)
  • Typical current rises from 250 mA with the ring light off to 410 mA when it is on. (S1)
  • UNO Q requires a suitable hub, while VENTUNO Q has an onboard USB-A port. (S1)

What happened

Arduino has introduced a USB camera accessory for the Linux side of UNO Q and VENTUNO Q boards. The camera uses a Sony IMX376 sensor and provides autofocus starting at 20 cm, a ring light, a privacy shutter and USB audio. It also includes a captive cable terminating in USB-A; UNO Q requires a suitable hub, while VENTUNO Q provides an onboard USB-A connection.S1

The accessory operates as a USB Video Class device, allowing supported Windows, macOS and Linux systems to recognize it without a separate camera driver. Its microphone appears as an independent USB Audio Class device. Arduino positions the product for Linux-side workloads such as object detection, gesture recognition and local vision-language applications.S1

Its headline capture mode delivers up to 3840 × 2160 at 30 fps in compressed MJPEG, but uncompressed YUY2 supports lower combinations: 1920 × 1080 at 5 fps, 1280 × 720 at 10 fps and 640 × 480 at 30 fps. Applications must negotiate the appropriate format, resolution and frame rate, and MJPEG adds host-side decoding.S1

Arduino recommends a powered hub when operating the ring light or attaching additional USB peripherals because the camera receives power through USB. As checked on October 19, 2026, the European store listed the camera at €35 including VAT, but delivery dates and final landed costs by destination remained unverified.S1

XAIPART take

Technical impact

XAIPART analysis: Engineers should treat the camera as a standard UVC peripheral feeding Linux rather than as a direct sensor interface to the microcontroller. Capture settings, host decoding, application support and processing throughput must be validated separately because nominal output resolution does not establish AI inference performance.

XAIPART analysis: Prototype work should test YUY2 at the required resolution against MJPEG at the same resolution, including decode load, latency and image quality. The source provides no tested latency, image-quality assessment or evidence that an App Lab model can process the maximum stream.

Market impact

XAIPART analysis: The accessory can shorten evaluation cycles for standard webcam functions, but UNO Q buyers may need to include a suitable hub in the bill of materials and schedule. VENTUNO Q users have a simpler connection path through the onboard port, although that does not equalize processing performance between the boards.

XAIPART analysis: Procurement should compare the complete USB power path rather than the accessory price alone. Hub capability, available port current, shipping, regional stock and software integration effort remain the practical landed-cost variables.

Action

XAIPART analysis: Request the datasheet and supported-host list during technical review, then confirm whether Linux applications can select the required format and frame-rate combination. Validate autofocus at the intended working distance and verify privacy-shutter and lighting requirements in the mechanical design.

XAIPART analysis: For prototypes using UNO Q, identify a powered USB-C hub with adequate headroom and document its role in the BOM. For production planning, obtain local stock and delivery confirmation because the source verified only a European store listing.

XAIPART Forecast

XAIPART analysis: XAIPART expects Arduino to keep UNO Q deployments dependent on an appropriately specified hub when the USB Camera is used with the ring light; by Q1 2027, buyer qualification should confirm whether the selected hub can sustain at least 450 mA plus the current drawn by any additional USB peripherals.

XAIPART analysis

Facts are as reported by the cited source. The design-in, sourcing and forward-looking statements above are XAIPART's analysis, not the source's claims. This is a single-source report; the camera, inference latency and image quality were not tested, and no delivery date was verified.

Corrections: none at publication. This brief will be updated with a timestamp if the source corrects its report.
