It is made from the same tough plastic and again features the Raspberry Pi logo etched onto it
Reverse motor: DIR = 0 PWM = PWM
This mini DC-DC step-down voltage converter module support 6-24V voltage input and 5V 3A output with input polarity reverse protection and output over-voltage protection
Outer diameter: 20mm
Line Tracking Sensor jumper wires It is made from theThe Line Tracking TCRT5000 infrared sensor emits infrared emitting diode continuously when no infrared rays emitted or reflected back is reflected back but the strength is not large enough, the phototransistor has been in the off state, and the output terminal of the module is high, indicating that the diode has been in the off state; in the object to be detected within the detection range, and the intensity of the reflected infrared rays is large
