It works with popular flight controllers like Pixhawk and Arduino-based systems. Ideal for autonomous hovering, indoor navigation, and stable aerial photography.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSensor Type\u003c\/td\u003e\n\u003ctd\u003eOptical Flow \u0026amp; ToF\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eUART (3.3V TTL)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e4.5V–5.5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;100mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eToF Range\u003c\/td\u003e\n\u003ctd\u003e0.1m–2m (indoors)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e28mm x 28mm x 7mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eIndoor drone with autonomous position and height hold\u003c\/li\u003e\n  \u003cli\u003ePrecision landing system for UAVs\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-autonomous-drone-obstacle-avoidance\"\u003eObstacle avoidance drone using ToF distance sensing\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eAutomated warehouse inventory drone with optical flow navigation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis module interfaces via UART and is compatible with Pixhawk, APM, Arduino, and Raspberry Pi boards. It works at 3.3V logic level but can tolerate 5V input with a simple level shifter. Pair it with a GPS module for robust outdoor position hold.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to 5V, GND to ground, TX to flight controller RX, and RX to flight controller TX. Ensure the sensor has a clear downward-facing view. Use a logic level converter if your controller operates at 5V to avoid damage.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
