Description

The Holybro H-Flow is a compact optical flow and distance sensor module that combines a PixArt PAA3905E1 optical flow sensor, a Broadcom AFBR-S50LV85D distance sensor, and an InvenSense ICM-42688-P 6-axis IMU. This all-in-one design simplifies installation while providing accurate motion tracking and distance measurement capabilities for UAV applications, with enhanced low-light performance through an onboard infrared LED.
