Questions
How big is the Level shifter adapter PCB?
It measures 35.6 × 30.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Level shifter adapter use?
45 parts, built around the ATTINY45-20SU, BC847, IRLML6401 and BAV70. 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 adapter KiCad files?
From the ZeroPhone/ZeroPhone-Mod-PCBs repository on GitHub, at the commit this page was made from: the board is level_shifter_adapter/level_shifter_adapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Level shifter adapter design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
