It delivers real-time horizontal movement data and precise distance-to-ground measurements, enabling stable altitude and position hold on custom drones. This module is essential for indoor navigation and autonomous flight projects where GPS is unavailable.\u003c\/p\u003e\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 + ToF (VL53L1X-based)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e3.3V – 5V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 100 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eToF Range\u003c\/td\u003e\n\u003ctd\u003e4 cm – 4 m (indoor, good lighting)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003eI2C \/ UART (selectable)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e25 × 15 × 5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eIndoor hovering drone with stable altitude and position lock\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/arduino-obstacle-avoidance-robot-kit-build-and-code-autonomous-car\"\u003eAutonomous delivery robot using floor tracking and obstacle avoidance\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/gesture-controlled-robotic-hand-kit-with-flex-sensors-and-arduino-nano\"\u003eGesture-controlled drone that follows hand movements precisely\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eLow-altitude survey drone for accurate mapping without GPS\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe module works with flight controllers running ArduPilot (via I2C), PX4, and Betaflight (with custom firmware). It supports 3.3V and 5V logic levels, making it compatible with Pixhawk, Omnibus, and Matek boards. For best results, pair with a vibration-damped mount.\u003c\/p\u003e\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eConnect VCC to a clean 3.3V or 5V output on your flight controller. Wire SDA\/SCL for I2C mode, or TX\/RX for UART. Ensure a solid common ground. Add a 100 µF capacitor near the module to suppress voltage spikes from motor ESCs.\u003c\/p\u003e\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing.
