Questions
What parts does the STM32F4 BuckConverter use?
58 parts, built around the STM32F405RGT6, MP2359DJ-LF-Z, USBLC6-2SC6 and B5819W. 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 STM32F4 BuckConverter KiCad files?
From the zzakiullah/stm32f4-eval repository on GitHub, at the commit this page was made from: the board is STM32F4_BuckConverter.kicad_pcb and its schematic STM32F4_BuckConverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32F4 BuckConverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask zzakiullah before reusing the design.
