Questions
How big is the Sensor PCB?
It measures 134.5 × 99.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sensor use?
20 parts, built around the LM339. 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 Sensor KiCad files?
From the marianomorel/docencia repository on GitHub, at the commit this page was made from: the board is PT4/TRABAJOS 2025 - GRUPOS/G7/sensor.kicad_pcb and its schematic PT4/ACTIVIDADES PT-IV/PROYECTO-KICAD/PROYECTO-KICAD/PROYECTO-KICAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask marianomorel before reusing the design.
