Lidar/dTOF sensor news

After various trials with 360deg lidars and their size, introduced mechanical vibrations and integration with not that big frames (8” in my case) I dropped the idea to have obstacles avoidance in my drone.

But seems there is a new hope for small drones to be able to “see” reasonable wide area with single sensor, no mechanical parts, no additional vibrations or magnetic interferences from lidar motor in compass readings.

This came into my attention: https://www.farnell.com/datasheets/4759648.pdf

Small, usable range up to 9m, reasonably high FOV - 72deg with 100Hz update rate. Can not wait to get my hands on one and do some testing.

If anyone has tested that please share some info.

Maximum background illumination is missing in the datasheet :sweat_smile:.

Will see. Justo ordered one :slight_smile:

In datasheet: “For outdoor use, it delivers excellent ranging performance even under
strong ambient light and is compatible with various cover glass materials”. So I guess that will depend on good 940nm filter.

Which distributor did you use?

Have you found a better price than Digikey’s $70?

I tempted to join the fun but I think I’ll hold off for a bit. Thanks for sharing this find with us. It looks very interesting.

I bought it from farnell for equivalent of about 58$, but they had only one in stock. And I bought the element itself, not PCB. I will design PCB myself with STM MCU reading this I3C and uart sending MSP or something suitable for ardupilot.

You’re a braver man than I. I found the datasheet very intimidating. It sure looks like there will be a crazy amount of data to process. I wish you luck and I hope you let us know how the project progresses.

Not that much… counting 4 bytes per point 2268 x 4 x 100Hz gives less than 1Mbyte/s.
DMA offloading transfer with I3C and UART - I am expecting to be able to use Cortex M33F based MCU for this, but we will see
