Questions
How big is the PCI2USB PCB?
It measures 22 × 80 mm and has 4 copper layers, 0.8 mm thick.
What parts does the PCI2USB use?
91 parts, built around the TPS2560DRC and TPS74401RGW. 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 PCI2USB KiCad files?
From the 3mdeb/PCI2USB repository on GitHub, at the commit this page was made from: the board is Kicad-Files/PCI2USB.kicad_pcb and its schematic Kicad-Files/PCI2USB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCI2USB design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3mdeb before reusing the design.
