I bought this PRLIDAR A1 2d scanner on amazon for about $100.
It outputs serial data at 115200BPS and in the mode I'm using, legacy scan mode,
it streams a 5 byte packet of a distance and angle pair about every degree at 5 revs per second.
That's 1800 points a second, 9000 bytes/sec. It has a faster mode but the packet format is trickier.
Data was coming back faster than I could plot it in the debugger...
When it is scanning, the angle you get back, isn't exactly 1 degree larger than the prior packet, but close.
It measures up to 12 meters away and has distance resolution of 1/4mm, angular resolution of 1/64degree.
I was adding a TFmini plus lidar unit to my drone and I couldn't help getting sidetracked by this thing.
I don't have anything in mind for it, but wanted to try it out.
They say it does not work outdoors in daylight.
In the video, you can barley see the scanner light up the cardboard as it scans across...
