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. For a comprehensive guide check out Setting up Optic Flow in INAV by digitalentity Check out all our Matek products! Specifications Optical Flow: PMW3901 Lidar: VL53L0X Interface UART Protocol: INAV MSP Working Range: 8cm~200cm Field of view: 42 degree(PMW3901), 27 degree(VL53L0X) Minimum Illumination >60Lux Input voltage: 4.5~5.5V Power Consumption: 40mA Size: 36*12mm,  2g Tips Be sure Optical Flow lens to ground >2cm for opflow initialization while FC starting up. Maximum range of VL53L0X is 2m,   Altitude hold 0~2m @ throttle 0~100% if VL53L0X is enabled. Any unused UART of FC supports it Sonar connection (Trig & Echo) has not been implemented Setting up Optic Flow in INAV   PDF by digitalentity Includes 1x Matek 3901 L0X Optical Flow & Lidar Sensor
