Questions
How big is the Level shifter PCB?
It measures 78.7 × 57.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Level shifter use?
8 parts, built around the 74LS126PC. 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 Level shifter KiCad files?
From the OpenElectronicsLab/level-shifter repository on GitHub, at the commit this page was made from: the board is level-shifter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Level shifter design in my own project?
Its repository states no licence, so its author keeps all rights: ask OpenElectronicsLab before reusing the design.
