Overview 

Achieve rock-solid position hold and sub-centimeter altitude stability without GPS.

The Mechintel Dual Optical Flow & DTOF LiDAR Module is an all-in-one vision-based navigation system engineered for micro-quadcopters, indoor drones, and autonomous mobile robots (AMRs). By fusing a high-speed downward-facing optical flow (PMW3901) sensor with a precision Direct Time-of-Flight (DTOF) laser rangefinder (VL53L1X), this module outputs real-time X/Y velocity vectors and absolute altitude (Z) data over a single UART interface.

Ideal for classroom STEM kits, university robotics labs, and custom ESP32, ArduPilot, PX4, and Arduino developer builds.

Key Features

  • Zero-GPS Indoor Loiter: Fly indoors or in GPS-denied environments with precision hover capability.
  • Integrated DTOF Laser Rangefinder: Eliminates altitude drift caused by barometer fluctuations or prop-wash, thanks to the ultra precise VL53L1X sensor.
  • Universal Compatibility: Outputs MSP and Mavlink protocol, which allows native support for ArduPilot, PX4, and custom microcontrollers (ESP32, STM32, Raspberry Pi Pico, Arduino).
  • Plug-and-Play Integration: Pre-calibrated optical alignment and integrated sensor fusion onboard—no complex optical lens alignment required.
  • Ultra-Compact & Lightweight: Engineered specifically for micro-frames where weight and power consumption are critical.
  • Dual Output Mode: Transmits synchronized X/Y pixel motion and distance data over standard serial (UART) or I2C/SPI protocols, which means one can directly access the attached sensors if required.
