Questions
What parts does the IR Sensor use?
9 parts, built around the LM358 and IR204-A-L. 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 IR Sensor KiCad files?
From the optimusprime1221/IR-Sensor repository on GitHub, at the commit this page was made from: the board is ir_sensor.kicad_pcb and its schematic ir_sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IR Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask optimusprime1221 before reusing the design.
