Questions
How big is the Levelshifter PCB?
It measures 18.9 × 13.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Levelshifter use?
12 parts, built around the AP7370-33W5 and BSS138. 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 Fa-b/Levelshifter repository on GitHub, at the commit this page was made from: the board is Levelshifter.kicad_pcb and its schematic 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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
