Questions
How big is the Stm32 devboard PCB?
It measures 40.9 × 42.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stm32 devboard use?
50 parts, built around the STM32F103CBT6, LSM303C and SM6T12A. 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 j23saw/stm32_devboard repository on GitHub, at the commit this page was made from: the board is stm32_devboard.kicad_pcb and its schematic stm32_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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
