Questions
How big is the Stm32 PCB?
It measures 39.7 × 24.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32 use?
28 parts, built around the AMS1117-3.3. 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 Stm32 KiCad files?
From the Annusingh002/custom-stm32-pcb repository on GitHub, at the commit this page was made from: the board is KiCad/stm32.kicad_pcb and its schematic KiCad/stm32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Annusingh002 before reusing the design.
