Automatic firmware detection and automatic protocol matching - using automatic detection technology, it can identify the connected flight controller firmware and automatically select the correct output protocol - without manual protocol settings. Laser ToF ranging achieves longer range and strong light performance - using a laser based ToF ranging sensor (LiDAR style ranging) designed specifically to resist sunlight interference. Provide extended ranging capability with a reflectivity of 0.02-12 meters at 90%. High precision ranging data with a 2 cm dead zone - ranging dead zone as low as 2 cm. Accuracy specifications: 4 cm (0.02-2 m @ 90% reflectivity) and 2% (Greater than 2 m @ 90% reflectivity), providing reliable distance/altitude input for low altitude control scenarios. 2-IN-1 Optical Flow+Ranging Sensor (Built in PMW3901) - Integrating PMW3901 optical flow with ToF ranging in a compact module, providing motion (flow) and distance information to support use cases related to positioning and altitude preservation. 100 Hz output+Universal Asynchronous Receiver/Transmitter+Compact 8G design - Output data at frequencies up to 100 Hz through Universal Asynchronous Receiver/Transmitter. Supports MAVLink v1 (ArduPilot/PX4), MSP v2 (INAV), and Micolink (FMT). Color: As Shown Material: PCB Package Contents: 1 * optical flow sensor 3 * accessories Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
