Connecting USB to TTL adapter

I am new to the Raspberry Pi/Navio2 connection. I am trying to hook up an optical flow sensor via a USB to TTL adapter to a Raspberry Pi 3B+ and Navio2 assembly. I am also using Ardupilot to see the data from the optical flow sensor. How can I set it up so that Ardupilot can detect the data from the pi’s USB port?

Hi @tenshi17cablepup18,

ArduPilot supports a limited number of optical flow sensors and has detailed tutorials for connecting each of them. Please check ArduPilot docs for more information.
