Questions
How big is the Stm32 minimal dev PCB?
It measures 53.3 × 35.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32 minimal dev use?
33 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 minimal dev KiCad files?
From the amrithHN/stm32_minimal_dev repository on GitHub, at the commit this page was made from: the board is stm32_minimal_dev.kicad_pcb and its schematic stm32_minimal_dev.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32 minimal dev 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).
