Questions
How big is the USBSplitter PCB?
It measures 28 × 55.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the USBSplitter use?
16 parts. 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 USBSplitter KiCad files?
From the peteEH/usb-splitter-basic-bmec-2025 repository on GitHub, at the commit this page was made from: the board is USBSplitter.kicad_pcb and its schematic USBSplitter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the USBSplitter design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
