Questions
How big is the Vi Fi PCB?
It measures 31.8 × 57.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Vi Fi use?
17 parts, built around the CS48520S, ESP-WROOM-02D-N4, MP1469GJ-Z and MSK12C02-SZ. 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 Vi Fi KiCad files?
From the Cooper7196/Vi-Fi repository on GitHub, at the commit this page was made from: the board is Vi-Fi.kicad_pcb and its schematic Vi-Fi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Vi Fi design in my own project?
Its repository states no licence, so its author keeps all rights: ask Cooper7196 before reusing the design.
