Questions
How big is the Interface PCB?
It measures 194.2 × 160 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Interface use?
92 parts, built around the RP2040, W25Q128JVPIQ, XC6210B332MR-G and ESD5Z5V0. 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 Interface KiCad files?
From the Kargo/MechBoard repository on GitHub, at the commit this page was made from: the board is Interface.kicad_pcb and its schematic Interface.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Interface design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kargo before reusing the design.
