5 FAQ
Q: Can I adjust the sensitivity of the sensors?
A: Absolutely. There is a blue potentiometer on the board to adjust detection sensitivity.
Q: Does it come with mounting screws?
A: The module includes the PCB and pins. Mounting screws are not included in the standard package.
Q: What is the main advantage of the 5-channel over the 3-channel?
A: The 5-channel module offers higher precision and smoother line tracking for complex paths.
Q: Does this module work with 3.3V microcontrollers?
A: Yes, the operating voltage range is 3.3V to 5V, so it is compatible with 3.3V logic.
Q: Is the output analog or digital?
A: The output is digital TTL. When the line is detected, the signal level changes.
