- Built-in ultra small lidar module
- CAN protocol to provide more reliable communication
- Built-in IMU module
- PMW3901 Optical Flow Sensor gives ranted from 80mm to infinty
Note: Before using the HereFlow, please download the instruction from ‘HereFlow’ section on Cubepilot.org.
The flow sensor should be mounted on the underside of the copter with the camera lens pointing downwards. The side of the sensor with the lens should be towards the front of the vehicle
