  • Zio Line Finder (Qwiic, four transceivers)
  • Building robots utilizing I2C
  • Four IR reflectance sensing submodules

The Zio Line Finder w/ Qwiic & 4 Transceivers is a version of a line following sensor array, intended for building robots that use I2C for communication between subsystems.

Like other line following sensor modules, it has four IR reflectance sensing submodules that can detect a lines position. A PCA9539A I/O expander is used to detect when a given submodules output voltage crosses its logic level threshold, indicating the detection of the line. When one of the submodule I/O channels is driven LOW, it indicates the presence of the line.

Four potentiometers allow for independent adjustment of the IR modules sensitivities to suit different robot platforms, accounting for differences in sensor mounting heights. Additionally, four LEDs provide a visual indicator for the detection status of each channel, making it easy to tune the sensitivity of each sensor channel.

As the PCA9539A has 16 digital I/O channels, the remaining 12 channels are broken out to standard pitch pin headers for users to utilize as needed.
