Holybro H-Flow optical flow and distance sensor module 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 six-axis IMU. This all-in-one design simplifies installation, while a built-in infrared LED improves visibility in low-light conditions. The H-Flow is equipped with a 4-pin CAN connector according to the Pixhawk standard, which ensures seamless integration with Pixhawk-compatible controllers via the CAN port. It uses the DroneCAN protocol and offers reliable and high-speed data transfer between the sensor and the flight controller.
