Centered on the three core demands of precision, convenience, and adaptability, the VM4331 series delivers customized solutions for diverse application scenarios. Each of the two modules boasts impactful highlights, effortlessly addressing ranging challenges in complex indoor and outdoor environments.

1. VM4331 MIPI Module
High Integration + High Precision: A Compact Powerhouse Resistant to Environmental Interference

As a core solution for size and cost-sensitive scenarios such as consumer electronics and smart home appliances, the MIPI module is built on high integration. It deeply integrates a large-format Single-Photon Avalanche Diode (SPAD) receiver array and a VCSEL laser emitter, while incorporating core components including SPAD detectors, VCSEL light sources and driver circuits, and optical lenses. This directly meets the requirements for miniaturization and low cost, with four key highlights:
Consistent High-Precision Ranging: Unaffected by object color, surface reflectivity, or texture variations, it enables stable detection of various materials such as metal, plastic, and fabric, ensuring consistent sensing across multiple scenarios.
Sub-Centimeter-Level Precision Output: Capable of generating image-level 3D sensing point clouds with sub-centimeter precision, it fully satisfies high-precision spatial sensing needs.
Stringent Safety Compliance: Adopting a sub-nanosecond light pulse design and an exclusive eye-safety control circuit, it strictly complies with Class 1 eye safety standards, achieving a perfect balance between performance and safety.
Strong Environmental Adaptability: Dual protection from narrow-band optical filters and built-in ambient light suppression algorithms minimizes ambient light noise. It delivers stable ranging performance of up to 12 meters indoors and 2.5 meters outdoors, and operates reliably under complex lighting conditions including strong and weak light.

2. VM4331 USB Module
Low Threshold + High Flexibility: A Plug-and-Play Tool to Accelerate 3D Sensing Deployment

Tailored for rapid prototyping and lightweight application needs, the USB module prioritizes ease of use, significantly lowering the development and verification threshold for 3D sensing technology. Its three key highlights directly address R&D pain points:
Plug-and-Play with Dual-Interface Compatibility: Integrated with a standard USB 2.0 data interface, it supports both USB Type-A and Type-C connections, and directly outputs standardized 3D point cloud data (including ToF ranging data, reflectivity, and grayscale), truly achieving "out-of-the-box connection and instant use".
Simplified Development, Multiplied Efficiency: Complete supporting software development tools are provided. Users do not need to delve into underlying technical details such as photoelectric calibration and histogram processing; they can directly call point cloud data to quickly build terminal application prototypes, significantly shortening the R&D cycle.
Flexible Customization for Multi-Scenario Adaptability: It supports configuring data output formats via parameter adjustment, enabling flexible balancing between transmission bandwidth constraints and business data requirements, and perfectly covers consumer-grade and industrial-grade lightweight 3D sensing scenarios.
