The MTF-02 packs an optical flow camera and a short-range ToF rangefinder into 1.0 gram — light enough for tiny whoops and 2–3 inch micros that could never carry a full-size sensor. It gives small indoor drones GPS-free position hold over a simple 50 Hz UART link, with ArduPilot, PX4, INAV and FMT support. Strictly an indoor sensor: sunlight saturates its receiver — for outdoor micro builds choose the MTF-02P.
Before you fly: the airframe comes first
An optical flow sensor corrects the flight controller's estimate — it cannot rescue a vibrating airframe. Balance props and check vibration first: the setup guide shows the exact checks for each firmware.
