The VL53L9 from STMicroelectronics, is a compact direct Time-of-Flight 3D LiDAR all-in-one module that sets a new benchmark in high-resolution sensing. The VL53L9 combines state-of-the-art features in a compact package, delivering AI-ready output data for low-compute edge AI systems on small microcontrollers (MCUs) and high-performance sensing across a wide range of applications, including robotics, industrial automation, smart buildings, AR/VR, and healthcare.
Offering an unprecedented 2,268 resolution zones (54 x 42) with a wide 54° x 42° field of view, enabling detailed 3D depth mapping and precise detection of small objects, contours, and edges. Leveraging ST’s proprietary stacked BSI SPAD sensor technology and innovative metasurface optical elements (MOE), the module delivers fast and accurate ranging from less than 5 cm up to 9 meters with up to 1% accuracy and a frame rate of 100 frames per second.
The VL53L9’s dual-scan flood illumination replaces traditional dot scanning, reducing motion artifacts, eliminating dead zones, improving small-object detection, and capturing complementary 2D infrared and 3D depth images. The all-in-one module further integrates on-chip dToF processing, a dedicated power management IC, and is fully calibration-free, simplifying integration and reducing system cost and complexity.
The module supports dual power supply operation (1,2 V and 3,3 V) and outputs data via MIPI or I3C interfaces, ensuring compatibility with diverse CPU architecture.

Editor's Choice Circuit & System Protection
As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
