Questions
How big is the USBBoard PCB?
It measures 27.9 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBBoard use?
48 parts, built around the CH340C, FS8205A, TC4056A and BC846. 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 USBBoard KiCad files?
From the eightonegulf/OpenController repository on GitHub, at the commit this page was made from: the board is Hardware/USBBoard/USBBoard.kicad_pcb and its schematic Hardware/GamecontrollerPeripheral/GamecontrollerPeripheral.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask eightonegulf before reusing the design.
