The VM4331 series is built around three core demands: Precision, Convenience, and Adaptability. It creates exclusive solutions for different application scenarios. The two major modules each feature key highlights, confidently addressing the ranging challenges in complex indoor and outdoor environments.
High Integration + High Precision, A "Miniaturization Tool" Unfazed by Environmental Interference

As a core solution for "size and cost-sensitive" scenarios such as consumer electronics and smart home devices, the MIPI module leverages high integration as its foundation. It deeply integrates a large-area Single-Photon Avalanche Diode (SPAD) receive array and VCSEL laser transmitter, while also incorporating core components like built-in SPAD detectors, VCSEL light sources and drive circuits, and optical lenses. It directly meets the needs for miniaturization and low cost, with four key highlights:

• Differentiation-Free Precision Ranging: Completely unaffected by differences in object color, surface reflectivity, or texture. It can stably detect various materials such as metal, plastic, and fabric, ensuring consistent perception across multiple scenarios.
• Sub-Centimeter Precision Output: It can generate image-level 3D perception point clouds with sub-centimeter precision, perfectly covering the demand for high-precision spatial perception.
• Stringent Safety and Compliance: Adopting a sub-nanosecond optical pulse design and exclusive eye-safe control circuitry, it strictly complies with Class 1 eye safety standards, balancing performance and safety.
• Strong Environmental Adaptability: Featuring dual protection of "narrowband filter + built-in ambient light suppression algorithm", it minimizes ambient light noise. It achieves stable indoor ranging of 12m and outdoor ranging of 2.5m, operating reliably in harsh lighting conditions such as strong light and low light.

VM4331 USB Module

Low Threshold + High Flexibility, A "Quick-Install Tool" Accelerating 3D Sensing Implementation

Targeting rapid prototype development and lightweight application needs, the USB module focuses on ease of use. It significantly lowers the barriers for developing and validating 3D sensing technology, with three highlights directly addressing R&D pain points:

• Plug-and-Play, Dual Interface Compatible: Integrating a standard USB2.0 data interface, it supports compatibility with both USB Type-A/Type-C interfaces. It can directly output standardized 3D point cloud information (including ToF ranging data, reflectivity, and grayscale), truly enabling "connect out of the box and use immediately".
• Simplified Development, Doubled Efficiency: Complete with a full set of software development tools, users don't need to delve into underlying technical details like 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 adjusting parameters to configure the data output format, enabling flexible balancing of "transmission bandwidth limitations" and "business data requirements". It perfectly covers consumer-grade and industrial-grade lightweight 3D sensing scenarios.

Full-Scenario Empowerment

With the core advantages of "high precision, small size, easy integration, and low cost", the VM4331 series modules are deeply adapted for multi-field applications, directly translating highlights into scenario value:

• Spatial Perception and Mapping: Leveraging millimeter-level precision and 12m indoor ranging capability, it achieves high-precision spatial positioning and map construction.
• Obstacle Avoidance and Collision Prevention: Differentiation-free ranging and strong environmental adaptability ensure accurate identification of various objects such as metal, plastic, thin wires, and carpets in complex environments, avoiding collision risks.
• Gesture Recognition: Image-level 3D point cloud output accurately captures gesture details, enhancing interaction sensitivity.
• 3D Modeling: Its small size makes it easy to integrate into terminal devices.
