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 the onboard infrared LED enhances visibility in low-light conditions.
- Integrated optical flow and rangefinder module
- PixArt optical flow sensor for accurate motion tracking
- Broadcom ToF sensor for precise distance measurement
- Infrared LED for optimal low-light performance
- DroneCAN protocol through a Pixhawk-standard 4-pin CAN connector
