Questions
How big is the Switch PCB?
It measures 174.1 × 47.5 mm and has 6 copper layers, 1.56 mm thick.
What parts does the Switch use?
105 parts, built around the PI7C9X2G404SLBFDEX, M24C04-WMN6TP, MPZ1608D101BTA00 and 3183-10110P1T. 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 Switch KiCad files?
From the neatstranger/pcie_switch repository on GitHub, at the commit this page was made from: the board is switch/switch.kicad_pcb and its schematic switch/PCIE_DOWNSTREAM.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Switch design in my own project?
Its repository states no licence, so its author keeps all rights: ask neatstranger before reusing the design.
