Description:
The Holybro H-Flow is a high-performance, compact optical flow and distance sensor module designed for precision navigation in drones and robotics. It combines the PixArt PAA3905E1 optical flow sensor, Broadcom AFBR-S50LV85D time-of-flight (ToF) distance sensor, and a 6-axis InvenSense ICM-42688-P IMU into a single unit. With a built-in infrared LED, the H-Flow excels even in low-light environments, making it ideal for indoor and GPS-denied navigation.
This module communicates using the DroneCAN protocol via a Pixhawk-standard 4-pin CAN connector, enabling easy and robust integration with Pixhawk-compatible flight controllers. It features a wide sensing range (80 mm to 30 m) and high reliability across diverse surface types and lighting conditions. Weighing just 15.2g with casing, it is an efficient solution for professional UAV applications requiring accurate motion tracking and altitude hold.
