It can be used directly after a simple configuration without a complicated development process. Optical Flow: PMW3901; Lidar: VL53L0X; Interface UART; Protocol: INAV MSP; Working Range: 8cm~200cm; Field of view: 42 degree(PMW3901), 27 degree(VL53L0X) Do you have an optical flow sensor on there? I'm not sure if it's supported in iNav, but Matek makes a very lightweight combined optical flow + laser range finder module that would seriously lock in your hover hold. It uses UART to output data and is compatible with mainstream open-source flight controllers such as Ardupilot, PX4 and INAV. It can be used directly after simple configuration To use optic flow capabilities of INAV you need two sensors - optic flow (to measure sliding)and rangefinder (to measure distance to surface). 'Laser altimeter' would be more descriptive. CAD$26. 2. I don't know much about these optical flow sensors other than they help the quad maintain altitude within a certain range. So I'm interested in using my Benewake TFmini Plus in conjunction. In practice this should work fine, but my problem is connectivity. 5. May 5, 2022 · I'm new to INAV. . 5mm, it is particularly suitable for drones of 3 inches or smaller, almost without A New Optic Flow&Lidar sensor for Ardupilot/PX4/INAV: MicoAir: Multirotor Drone Electronics: 18: Mar 01, 2024 02:13 PM: Discussion: Test of MTF-01 OPTICAL FLOW & LIDAR SENSOR on 2-Inch FPV Drone: linkall: Multirotor Drone Electronics: 0: Oct 30, 2023 10:32 AM: Discussion: add optical flow sensor to uart occupied by BT module: spikey1973 Make sure to find wholesale flow meters extensive collections of inav optical flow at Alibaba. 1. Culd you please provide me with documentation ? I dont know where to start. Skip to content Shipping from Central FL within 24 hours!
