Questions

How big is the SensorArray PCB?

It measures 36 × 144.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SensorArray use?

36 parts, built around the ITR8307 and PCA9557PW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the SensorArray KiCad files?

From the LaboratorioGluon/Velocista-Marrajo repository on GitHub, at the commit this page was made from: the board is Schematics/SensorArray/SensorArray.kicad_pcb and its schematic Schematics/LineFollower/LineFollower.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SensorArray design in my own project?

Its repository states no licence, so its author keeps all rights: ask LaboratorioGluon before reusing the design.
