Questions
How big is the Usbsupply PCB?
It measures 50 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Usbsupply use?
78 parts, built around the STM32F030F4P6, CP2104-F03-GM, LTC3883EUH-1#PBF and IP4234CZ6. 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 Usbsupply KiCad files?
From the brightcloudy/usbsupply repository on GitHub, at the commit this page was made from: the board is usbsupply.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Usbsupply design in my own project?
Its repository states no licence, so its author keeps all rights: ask brightcloudy before reusing the design.
