Questions
What parts does the Boostier use?
7 parts, built around the SN74LV1T126DBVR-TP and TLV61070ADBV. 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 Boostier KiCad files?
From the jusdisgi/boostier repository on GitHub, at the commit this page was made from: the board is boostier.kicad_pcb and its schematic boostier.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Boostier design in my own project?
Its repository states no licence, so its author keeps all rights: ask jusdisgi before reusing the design.
