Optical flow options-2020

It should work as it has the Ardupilot settings. Quality and performance, not so sure. I didn’t use it before but from the same IC family. PMW3901 vs PAW3903

the only difference I see is the low-light operating condition.

But if you need a height like 100m, then can consider standalone optical flow + external rangefinder, which is my setup (Hereflow + LW20/C set to rngfnd1).
