Meet LightWare LiDAR’s SF45: the world’s smallest scanning microLiDAR designed for autonomous drones and robots. It gives these machines eyes to facilitate better navigation and fewer crashes. The SF45 provides position, distance and proximity sensing to drones and UGVs. It can detect obstacles at 50m in daylight.
This LiDAR is compatible with Ardupilot/PX4 and has APIs for Raspberry Pi and Arduino. It weighs only 59g. You can find out more about it here.
