The H-Flow is a compact and lightweight optical flow and rangefinder module designed to provide high-accuracy motion and altitude data for precise and stable navigation in GNSS-denied environments. It combines a PixArt optical flow sensor, a Broadcom distance sensor, and an InvenSense 6-axis IMU, as well as an infrared LED for enhanced visibility under low-light conditions.
The easy-to-install module utilizes the DroneCAN protocol, and includes a Pixhawk-standard 4-pin CAN connector for seamless integration with a wide range of UAV flight controllers.
