5. Octopus 2 Channel Tracking Module

5.1. Introduction


Octopus 2 Channel Tracking Module has integrated two groups of reflective infrared pair diode, which can be used to identify black lines. This module is usually used to make line tracking smart cars. We can design black track at will and make our cars follow it through programming.

5.2. Characteristics


  • Strong anti-interference by using infrared detection.

  • Positioning holes are compatible with main-stream smart car chassis.

  • Equipped with two 3-pin wire GVS jumper cables and 4-pin soldering plate, the two 3-pin ports can be connected directly to two GVS wires.
