I've hooked up 2D LiDARs to Raspberry Pi, wrote Python library lds2d

This open-source project provides a Python library, lds2d, that enables users to interface with over 23 models of 2D LiDAR sensors (including LDROBOT, YDLIDAR, and RPLIDAR) via a Raspberry Pi. It is designed for robotics enthusiasts and developers who want to quickly experiment with LiDAR data without needing physical hardware, as it includes a simulation mode for instant testing. The project is interesting because it dramatically lowers the barrier to entry for LiDAR-based robotics prototyping, offering broad hardware support and instant, no-cost experimentation.
