Questions
How big is the STM32 USB BUCK PCB?
It measures 65.8 × 53.3 mm and has 4 copper layers, 4.69 mm thick.
What parts does the STM32 USB BUCK use?
51 parts, built around the MP2359DJ-LF-Z, USBLC6-2SC6, AO3401A and B5819. 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 USB BUCK KiCad files?
From the Omarfayed412/STM32_USB_BUCK repository on GitHub, at the commit this page was made from: the board is STM32 + USB + Buck.kicad_pcb and its schematic STM32 + USB + Buck.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32 USB BUCK design in my own project?
Its repository states no licence, so its author keeps all rights: ask Omarfayed412 before reusing the design.
