Questions
How big is the Stm32f042 board PCB?
It measures 41.6 × 18.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Stm32f042 board use?
27 parts, built around the USBLC6-2SC6 and BK0603HS330-T. 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 Stm32f042 board KiCad files?
From the jedp/STM32F042-dev-board repository on GitHub, at the commit this page was made from: the board is stm32f042_board.kicad_pcb and its schematic stm32f042_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stm32f042 board design in my own project?
Its repository states no licence, so its author keeps all rights: ask jedp before reusing the design.
