Description

This sensor works basically the same way as an optical mouse, helping your iNAV quad to maintain position without GPS! This module also integrates a laser time-of-flight range sensor. Check out Paweł Spychalski's video below.

        Slick part

        "Awesome little board that includes optiflow and lidar in a tiny for factor. Can't beat the price either!"

        Love this affortable MATEKSYS sensors

        "usually sensors like this tend to be expensive or not that easy to use so this is perfect for my tests"

        The Secret to Stability

        "If you want your drone to stay in one place, and I mean actually hold position and not just loiter, this is the sensor you're looking for. It has some trouble over fuzzy surfaces like grass, but iNav handles it all automatically to greatly improve tracking. Adding this took my POSHOLD drift from about 5 meters of drift down to 1."

        — Renny (5/5)

        Good sensor

        "Good sensor"

        — Diego I. (5/5)

        Perfect finishing touch!

        "Great little unit for using with INav. Wiring and configuration are pretty straightforward. Great addition for surface mode and position hold."

        — ROBERT M. (5/5)

        Must be low to ground

        "The Lidar and optical flow seem to work when printing out debugging messages. However, I can't seem to get readings beyond 1M (despite the specs saying 2M max)."

        — Stephen Y. (4/5)

        Put on my 7inch inav

        "Put on my 7inch inav build. Fits on kolas 7 easy"

        Q&A

        Hi , it works to configure betaflight or just for INAV.
        If there are options to select it in the ports setup then it would work I think
