This is my first PCB project. It took me around 20 hours. It is a small Linux computer that is the size of a business card. Based off of Allwinner F1C200s.
Around $5 or so per card? It is not too bad.

Questions
How big is the BusinessCard PCB?
It measures 89 × 51 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BusinessCard use?
39 parts, built around the F1C200S, JW5211 and W25Q80DVSNIG. 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 BusinessCard KiCad files?
From the JubilantMarmot/pcc5 repository on GitHub, at the commit this page was made from: the board is BusinessCard.kicad_pcb and its schematic BusinessCard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BusinessCard design in my own project?
Its repository states no licence, so its author keeps all rights: ask JubilantMarmot before reusing the design.
