Questions
How big is the STM32-devboard PCB?
It measures 20 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32-devboard use?
29 parts, built around the STM32F103C8T6 and 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-devboard KiCad files?
From the Lukaesque/STM32-devboard repository on GitHub, at the commit this page was made from: the board is STM 32 devboard.kicad_pcb and its schematic STM 32 devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32-devboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lukaesque before reusing the design.
