Good value for money

One sensor was slightly less sensitive than the others but still adjustable. Good performance for the price point.

Okay product

Wish it came with a cable harness. Had to solder my own headers which took extra time. Sensor works fine though.

Highly sensitive

Detects lines very accurately even at higher speeds. The 8 channels provide great resolution for smooth turning.

5 FAQ

Q: What is the maximum current draw?

A: The module draws approximately 20mA per channel when active, plus standby current for the LEDs.

Q: Can it detect colored lines like red or blue?

A: It detects contrast rather than specific colors. It works best with dark lines on light surfaces or vice versa.

Q: Is this compatible with Raspberry Pi GPIO?

A: Yes, this module is compatible with Raspberry Pi GPIO pins as long as you match the voltage levels.

Q: Does it come with mounting screws?

A: No, mounting screws are not included in the package. Standard 3mm screws fit the holes.

Q: Is the detection distance fixed?

A: No, the detection distance is adjustable via the potentiometer located on the PCB for each channel.
