The VI4302 is a System-on-Chip (SoC) that achieves distance measurement functionality based on Single-Photon Avalanche Diode (SPAD) photoelectric conversion devices. Boasting advantages such as a single-power-supply low-power-consumption system, high-performance ranging, high stability, and strong compatibility, it provides a highly integrated and cost-effective solution for pain point scenarios including LiDAR point cloud quality optimization, charging station recognition, and glass door collision avoidance. This chip is suitable for various applications such as robotic vacuums, service robots, and unmanned aerial vehicles (UAVs).
