Holybro H-Flow Optical Flow and Distance Sensor Module - DroneCAN, Pixhawk 4-Pin
The Holybro H-Flow is a high-integration sensor module combining an optical flow sensor, a long-range ToF distance sensor, and a 6-axis IMU. It communicates via DroneCAN over a Pixhawk-standard 4-pin CAN interface, providing precise motion tracking and altitude data for UAVs and robotics in GPS-denied environments.
Features
- Integrated PixArt PAA3905E1 optical flow sensor for precise 2D motion tracking.
- Broadcom AFBR-S50LV85D ToF sensor measures distances from 80 mm to 30 meters.
- TDK InvenSense ICM-42688-P 6-axis IMU (accelerometer + gyroscope) for enhanced motion sensing.
- DroneCAN protocol support via 4-pin CAN connector for robust Pixhawk integration.
- Built-in IR LED enables reliable operation in low-light conditions (>5 lux).

The H-Flow module integrates three distinct sensing technologies into a single compact unit. The PixArt optical flow sensor uses image correlation to detect lateral movement relative to the ground, while the Broadcom ToF sensor employs infrared time-of-flight principles for accurate, direct distance measurement. The integrated TDK InvenSense IMU provides inertial data to complement and stabilize the optical flow and ranging outputs.
Designed for professional UAV applications, the module communicates via the DroneCAN protocol, ensuring robust, low-latency data transmission to compatible flight controllers like Pixhawk. Its lightweight, shielded casing and included mounting hardware facilitate easy integration into airframes, supporting precise navigation, position hold, and obstacle avoidance in both indoor and outdoor environments.
