PX4FLOW – Smart Camera

QUICK START – HARDWARE VERSION 1.3

Description Features

Connectors and Dimensions

PX4Flow is an optical flow smart camera. It has a native

resolution of 752×480 pixels and calculates optical flow

on a 4x binned and cropped area at 250 Hz (bright,

outdoors), giving it a very high light sensitivy.

Unlike many mouse sensors, it also works indoors and

in low outdoor light conditions without the need for an

illumination LED at 120 Hz (dark, indoors). It can be

freely reprogrammed to do any other basic, efficient low-

level computer vision task.
