This tracking module features four infrared probes with an optimized spacing layout for precise line tracking. The two inner probes accurately detect the black line, while the outer probes assist with early line detection and provide additional support for curve tracking. It can effectively handle challenging tracks, including 90° turns.

The module includes a knob-type adjustable resistor and professional amplifier circuitry to fine-tune sensor sensitivity. It can be connected to a smart car or expansion board via cables (including DuPont cables) for a wide range of experiments. The design also includes mounting holes for copper columns and screws, allowing for further customization.

Key Features:

• High-quality infrared probes with a 4-way operation comparator circuit
• 1.6mm thick, impact-resistant PCB
• High precision for reliable tracking
• Adjustable sensitivity with a knob for fine-tuning
