Awesome 2D (low-cost) LiDAR list - specs, protocols, identification photos/videos, wiring, code, model versions, performance (TODO)

Please note - some of the information in the table below may be incorrect.

• some LiDAR/LDS models do not have official datasheets available publically 🫤
• some LiDAR/LDS models evolve over time - their specs change, while the model name remains unchanged
• maximum distance specification is often poorly defined (needs object reflectivity and ambient illumination specified)
• ambient light resistance is often poorly defined as well (needs object reflectivity, distance to object and ambient light spectrum)

Please also see this blog post and library.
