Questions
How big is the LevelShifter PCB?
It measures 122.7 × 104.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LevelShifter use?
112 parts, built around the LM324AD, MAX232N, AP63203WU and BAV16W. 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 LevelShifter KiCad files?
From the FontysMinorAR/LevelShifter repository on GitHub, at the commit this page was made from: the board is PCB/LevelShifter.kicad_pcb and its schematic PCB/LevelShifter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LevelShifter design in my own project?
Its repository states no licence, so its author keeps all rights: ask FontysMinorAR before reusing the design.
