A conveyor module includes an elongate frame to which a looped conveyor track is mounted. The frame includes first and second end housings which include end pulleys for the conveyor track. The frame also includes a drive housing located at a mid-portion thereof which houses the drive motor for the conveyor track. The conveyor module is a discrete independently driven unit with an upper portion (running surface) of the conveyor track in a planar orientation for conveying items thereon in use. The conveyor module can include additional smart features. A warehouse floor arrangement uses a plurality of side by side conveyor modules being identical and grouped into banks.
