Questions
How big is the Start PCB?
It measures 69.5 × 49.7 mm and has 2 copper layers, 1.2 mm thick.
What parts does the Start use?
32 parts. 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 Start KiCad files?
From the Micro9261/STM32F103_DevBoardv1 repository on GitHub, at the commit this page was made from: the board is Start.kicad_pcb and its schematic Start.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Start 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).
