The SparkFun Default KiCad Setup is a complete KiCad project that contains a schematic and PCB. These are meant to be used as the starting point for a new KiCad project. Additionally, this project's settings can be imported into KiCad for things like layer stackup, DRC warnings, trace and via defaults, and other commonly used settings that need to be set, but usually only once.

Questions
How big is the SparkFun Qwiic 1U Breakout PCB?
It measures 25.4 × 25.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SparkFun Qwiic 1U Breakout use?
67 parts, built around the BSS138 and PMEG4005EJ. 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 SparkFun Qwiic 1U Breakout KiCad files?
From the sparkfun/SparkFun_Default_KiCad_Setup repository on GitHub, at the commit this page was made from: the board is Example-Qwiic 1U Breakout/SparkFun_Qwiic_1U_Breakout.kicad_pcb and its schematic Example-Basic Board/SparkFun_Basic_Board_Example.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SparkFun Qwiic 1U Breakout design in my own project?
Its repository states no licence, so its author keeps all rights: ask sparkfun before reusing the design.
