DroneCAN Optical Flow & Range Sensor Board

The DroneCAN Optical Flow & Range Sensor Board is a high‑precision motion and proximity module designed for advanced UAV navigation and low‑altitude control. It integrates the PMW3901 optical flow sensor, delivering reliable XY motion estimation even in low‑texture environments. Complementing this, the VL53L8 3D time‑of‑flight sensor provides accurate distance measurements with multi‑zone ranging, enabling precise height‑hold, obstacle detection, and terrain‑following capabilities.

A BH1750F ambient light sensor ensures optimal flow performance by monitoring scene illumination and enabling adaptive exposure control. Fully compatible with DroneCAN, the board offers deterministic communication, robust noise immunity, and seamless integration with ArduPilot and modern CAN‑enabled flight controllers.

Designed for multirotors, fixed‑wing aircraft, and robotics platforms requiring stable low‑altitude flight and reliable motion sensing, this module delivers professional‑grade performance in a compact, lightweight form factor.
