From the project

USB accessory device with VL53L9 Time of Flight sensor (dToF 3D LiDAR) & 6-axis IMU

A compact and low-cost USB device with integrated LiDAR sensor and IMU. This hardware node packages STMicroelectronics' VL53L9 advanced direct Time-of-Flight (dToF) matrix LiDAR with a 6-axis IMU into a plug-and-play USB-C device. Designed for mobile robotics, micro-UAVs, and academic SLAM research. The hardware is designed in KiCad 10.

Per the VL53L9CX datasheet (DS14879, Table 2), the I3C interface is specified for a 12.5 MHz bus clock and a 12.5 Mbps output data rate. Full resolution is hard-limited to 30 Hz. Two pre-configured profiles are available:
