Product detailed description

Optical Flow and Distance Sensor Module Holybro H-Flow

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.

The H-Flow features a Pixhawk-standard 4-pin CAN connector, ensuring seamless integration with Pixhawk-compatible controllers via the CAN port. Utilizing the DroneCAN protocol, it offers reliable and high-speed data transmission between the sensor and the flight controller.
