Vadzo Imaging breaks down the differences between USB 3.2 Gen 1 and USB 3.2 Gen 2×2 and maps each generation to the right cameraand application through the Falcon-821CRS 8MP USB Color rolling shutter camera product, Falcon-900MGS 3MP Monochrome Global Shutter USB camera product, Vajra-2020MRS 20MP Monochrome Rolling Shutter USB camera product and Vajra-1335CRA 13MP Autofocus USB camera product so embedded vision engineers can stop over-engineering interface selection and start matching bandwidth to sensor output requirements.
FORT WORTH, TX / ACCESS Newswire / May 6, 2026 / Vadzo Imaging, a provider of embedded and machine vision camera products, today publishes a technical guide on USB 3.2 camera bandwidth selection covering the practical differences between USB 3.2 Gen 1 and USB 3.2 Gen 2×2 and how each generation maps to specific sensor outputs across the Falcon and Vajra USB 3.2 camera portfolio.
The guide is anchored to four production USB 3.2 camera products: the Falcon-821CRS Onsemi AR0821 USB camera delivering 8MP 4K HDR imaging on USB 3.2 Gen 1, the Falcon-900MGS Sony IMX900 USB camera delivering 3MP Monochrome Global Shutter imaging on USB 3.2 Gen 1, the Vajra-2020MRS Onsemi AR2020 USB 3.2 Gen 2×2 camera delivering 20MP Monochrome Rolling Shutter imaging and the Vajra-1335CRA Onsemi AR1335 Autofocus USB 3.2 Gen 2×2 camera delivering 13MP Color Autofocus imaging. Together, these products form a USB 3.2 camera portfolio that covers every primary embedded vision bandwidth requirement from 5 Gbps single-lane to 20 Gbps dual-lane operation.
Why USB 3.2 Generation Selection Matters Before Sensor Selection
The most common USB 3.2 camera specification mistake embedded vision engineers make is selecting a sensor first and discovering bandwidth limitations at integration. USB 3.2 Gen 1 delivers a theoretical 5 Gbps throughput with a practical ceiling near 400 MB/s. USB 3.2 Gen 2 doubles that to 10 Gbps. It can support higher-resolution sensors than Gen 1, but it does not provide the same headroom as USB 3.2 Gen 2×2 for sustained uncompressed high-resolution output at full performance. USB 3.2 Gen 2×2 combines two Gen 2 lanes to reach 20 Gbps throughput, which is the only USB interface that can sustain uncompressed 20MP output at usable frame rates without resolution compromise.
A 3MP USB Global Shutter camera like the Falcon-900MGS produces manageable raw output that fits comfortably within USB 3.2 Gen 1 throughput limits. An 8MP USB Color camera like the Falcon-821CRS sits at the upper boundary of Gen 1 operation at full resolution and full frame rate. A 20MP USB camera like the Vajra-2020MRS and a 13MP Autofocus USB camera like the Vajra-1335CRA require USB 3.2 Gen 2×2 to maintain uncompressed output at the resolutions and frame rates those sensors deliver.
Vadzo Imaging’s USB 3.2 camera portfolio is structured around this bandwidth reality. The Falcon series occupies USB 3.2 Gen 1 with sensors whose output fits that generation. The Vajra series occupies USB 3.2 Gen 2×2 with sensors whose high-resolution demands require the wider bandwidth that dual-lane Gen 2 operation provides.
Falcon-821CRS Onsemi AR0821 | 8MP 4K HDR USB 3.2 Gen 1 Color Rolling Shutter Camera Product
The Falcon-821CRS is an 8MP USB Color camera product built on the Onsemi AR0821 HyperLux sensor, a 1/1.7-inch BSI CMOS with 2.1 µm DR-Pix pixel technology delivering 8MP (3848 x 2168) with embedded HDR exceeding 140 dB. As an Onsemi AR0821 USB 3.2 Gen 1 Camera, the Falcon-821CRS is the USB 3.2 camColourera selection for embedded vision deployments where light conditions shift continuously, and standard dynamic range is insufficient.
The 8MP rolling shutter camera configuration addresses the specific challenge of mixed illumination environments found in UAV aerial missions, drone camera payloads, medical device camera integration, and warehouse automation, where partial shadowing, reflective surfaces, and artificial lighting all appear in a single frame. The onboard ISP with HDR processing, Auto Exposure, and Auto White Balance manages these transitions automatically without manual parameter adjustments. The 8MP color rolling shutter camera output moves comfortably within USB 3.2 Gen 1 throughput at 4K and 1080p resolutions, making it the correct USB 3.2 Gen 1 camera selection for HDR deployments that do not require the bandwidth headroom of Gen 2×2.

Falcon-900MGS Sony Pregius S IMX900 | 3MP Monochrome Global Shutter USB 3.2 Gen 1 Camera Product
The Falcon-900MGS is a 3MP USB Global Shutter camera product built on the Sony Pregius S IMX900, a fourth-generation stacked global shutter CMOS sensor with 1/3.1-inch format, 2.25 µm pixel pitch, and 3.2MP (2064 x 1552) resolution. As a Sony IMX900 USB camera, it delivers the combination of true global shutter accuracy, Quad HDR up to 120 dB, and enhanced NIR sensitivity in a compact IMX900 USB Gen 1 camera module purpose-built for motion-critical machine vision.
The 3MP Monochrome Global Shutter camera configuration eliminates rolling shutter skew for AGV camera navigation, biometric camera capture, automation camera inspection lines, and UAV camera platforms where lateral movement or vibration would introduce geometric distortion with a rolling shutter sensor. The 3MP USB camera output at 3.2MP sits within the USB 3.2 Gen 1 bandwidth envelope at full resolution and full frame rate, making it the bandwidth-efficient choice for motion-accurate imaging without requiring the 20 Gbps interface. NIR sensitivity at 850 nm and 940 nm makes this 3MP Monochrome camera the correct selection for biometric camera deployments, document scanning camera pipelines, and structured light inspection systems operating under infrared illumination.

Vajra-2020MRS Onsemi AR2020 | 20MP Monochrome Rolling Shutter USB 3.2 Gen 2×2 Camera Product
The Vajra-2020MRS is a 20MP USB camera product built on the Onsemi AR2020, a high-resolution monochrome CMOS sensor delivering 20MP (5544 x 3694) output that requires the full 20 Gbps throughput of USB 3.2 Gen 2×2 to sustain uncompressed output at usable frame rates. No USB 3.2 Gen 1 camera product can carry uncompressed 20MP output because the 5 Gbps single-lane ceiling is insufficient for the data volume that the sensor produces.
As an Onsemi AR2020 USB 3.2 Gen 2×2 camera, the Vajra-2020MRS is the 20MP USB camera selection for digital pathology camera systems, document scanning camera installations, high-resolution kiosk camera deployments, and automation camera lines where maximum spatial resolution per frame is the primary requirement. The 20MP Monochrome Rolling Shutter camera configuration captures maximum photon detail per pixel with the Bayer filter removed, making it the correct 20MP USB rolling shutter camera for inspection systems operating under controlled illumination, where rolling shutter motion distortion is a manageable variable. The 20MP Monochrome Rolling Shutter camera output demands the dual-lane 20 Gbps architecture that USB 3.2 Gen 2×2 provides and cannot be accommodated on any lower generation interface without resolution or frame rate compromise.

Vajra-1335CRA Onsemi AR1335 | 13MP Color Autofocus USB 3.2 Gen 2×2 Camera Product
The Vajra-1335CRA is a 13MP Autofocus USB camera product built on the Onsemi AR1335, a 1/3.2-inch BSI CMOS sensor delivering 13MP (4208 x 3120) with VCM-based autofocus covering 100mm infinity. As an Onsemi AR1335 Autofocus USB 3.2 Gen 2×2 camera, the Vajra-1335CRA resolves the two simultaneous challenges that fixed-focus rolling shutter camera products cannot address: maintaining sharp focus across variable subject distances and sustaining full 13MP output over a USB interface without compression.
The 13MP Autofocus camera operates on USB 3.2 Gen 2×2 because the 13MP rolling shutter camera output exceeds what a single USB 3.2 Gen 1 lane can carry at full resolution and full frame rate. The VCM autofocus mechanism covering 100mm to infinity makes this 13MP Color Rolling Shutter camera the correct selection for UAV drone camera deployments on inspection and mapping missions, document scanning camera systems, kiosk camera installations where subject distance changes, and medical device camera applications where focus must track automatically without operator intervention. Two FOV variants at 74 degrees DFOV and 127 degrees DFOV give optical flexibility within the same Onsemi AR1335 Autofocus USB camera platform.

Both SDKs support C, C++, C#, and Python with compatibility across Windows, Linux, Android, NVIDIA Jetson, and Raspberry Pi platforms.
“OEMs often assume the interface decision is just about bandwidth, but the real cost shows up in integration overhead late in the design cycle. That’s why we structured the Falcon and Vajra USB 3.2 camera portfolio around bandwidth-matched sensor output, with a common SDK, consistent optics, and unified ISP tuning. The right USB interface isn’t just about specs; it’s about how quickly you can move from evaluation to production without redesigning your pipeline.” – Alwin Vincent, Product Manager, Vadzo Imaging.
Frequently Asked Questions
USB 3.2 Gen 1 vs Gen 2×2 for cameras: which do I need?
The decision comes down to your sensor’s raw data output at your target resolution and frame rate. USB 3.2 Gen 1 has a practical throughput ceiling near 400 MB/s, which is sufficient for sensors up to 8MP at standard frame rates, covering the Falcon-821CRS 8MP color camera and the Falcon-900MGS 3MP global shutter camera. USB 3.2 Gen 2×2 runs two Gen 2 lanes in parallel for 20 Gbps throughput, and is the only USB interface that can sustain uncompressed output from high-resolution sensors like the 20MP AR2020 in the Vajra-2020MRS or the 13MP AR1335 in the Vajra-1335CRA. If you select the sensor first and discover the bandwidth gap at integration, a board redesign is typically required.
What is the difference between the Falcon series and the Vajra series USB 3.2 camera products?
The Falcon series operates on USB 3.2 Gen 1 and houses sensors whose output fits within its 5 Gbps theoretical throughput: the 8MP rolling shutter camera AR0821 and the 3MP USB Global Shutter camera IMX900. The Vajra series operates on USB 3.2 Gen 2×2 and houses sensors that require the 20 Gbps dual-lane throughput: the 20MP Monochrome Rolling Shutter camera AR2020 and the 13MP Color Rolling Shutter camera AR1335 with autofocus. The interface generation is matched to the sensor output rather than the reverse.
Which USB 3.2 camera product is recommended for both high resolution and autofocus, such as drone inspection or kiosk document capture?
The Vajra-1335CRA Onsemi AR1335 Autofocus USB 3.2 Gen 2×2 camera is the recommended selection. Its 13MP resolution sustains the spatial detail required for document scanning camera and inspection drone camera use cases, and the VCM autofocus covering 100mm to infinity removes the focus management requirement from the operator or system software.
Do all four USB 3.2 cameras work with the same SDK and development environment?
Yes. All Falcon and Vajra USB 3.2 camera products are supported by the VISPAARC SDK, which provides programmatic control over streaming, ROI, exposure, autofocus, triggers, GPIO, and firmware updates from a single API. The SDK supports C, C++, C#, and Python across Windows, Linux, Android, NVIDIA Jetson, and Raspberry Pi platforms. This means a team evaluating the Falcon-900MGS for a robotics project and later scaling to the Vajra-2020MRS for higher-resolution inspection does not need to rewrite the software integration layer – the same SDK calls apply across the portfolio.
What is a USB 3.2 camera, and how is it different from USB 3.0 cameras?
A USB 3.2 camera refers to cameras built on the USB 3.2 interface standard, which includes Gen 1 (5 Gbps), Gen 2 (10 Gbps), and Gen 2×2 (20 Gbps) bandwidth configurations. USB 3.0 is functionally equivalent to USB 3.2 Gen 1 at 5 Gbps, while newer USB 3.2 generations enable higher-resolution sensors to operate at full performance. Vadzo Imaging’s USB 3.2 camera portfolio focuses on Gen 1 and Gen 2×2 configurations, aligning bandwidth directly with sensor output requirements.
