The flow_raw debug shows that gyro and optical flow are similar in shape. Ambient Light Demand of Optical Flow: >60Lux; Optical Flow Working Distance: >8cm; Power Consumption: 200mW (40mA@5V) Supply voltage: 5V; Protocol. You switched accounts on another tab or window. the drone hover above 3-4 meters, when i switch on altthold mode ,the drone decrease altitude until it almost touch the ground,and it throttles up and increases altitude to 6-7meter, and than decrease slowly. FULL VIDEO -- https://www. Jul 22, 2021 · INAV Matek 3901 Optical Flow Position hold Test Althold Poshold Surface Mode OK iNAV를 이용한 레이싱드론 기체 말뚝호버링(Position Hold + Alt Hold) 시연 영상 입니다. Nov 28, 2024 · Tutorial From OscarLiang How to Set Up Optical Flow & Rangefinder Sensors in iNav – Position/Altitude Hold for FPV Drones Video Tutorial Optical Flow: PMW3901; Lidar: ST VL53L0X (max. MTF-01 is an optical flow ranging integrated sensor developed by MicoAir Technology. When the RC6 value is in the low position, SRC1(GPS) will be used, and in the middle position, SRC2(Optical flow)will be use. I don't know much about these optical flow sensors other than they help the quad maintain altitude within a certain range. There are two I2C ports on this FC. I would like to know if it will suffice to connect the breakout board to the SPI of an Ardupilot supported Flight Controller to use it or I am missing something. I want to connect FC to Raspberry Pi and read data from lidar/optical flow and GPS sensors. MATEK Optic Flow / Lidar board C o n n e c t i n g a n d c o n f i gu r i n g t h e h a r d w a r e Nov 7, 2022 · Same here, im only using a baro and a Matek 3901-L0X optical flow/lidar sensor. olsmmu fbro cuvl jfzhs vjvkny hzpx bagp xdvaho jbb ycagy
