Pcb tutorial
my personal goal is to design a pcb for a split keyboard by the end of august 2024. so right now im starting off my learning process by following a tutorial on how to make a 2x2 keypad (gotta start small)

Questions
How big is the Pcb tutorial PCB?
It measures 81 × 38.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pcb tutorial use?
24 parts, built around the ATMEGA32U4-AU. 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 Pcb tutorial KiCad files?
From the zyx-db/kb_pcb_tutorial repository on GitHub, at the commit this page was made from: the board is pcb-tutorial.kicad_pcb and its schematic pcb-tutorial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb tutorial design in my own project?
Its repository states no licence, so its author keeps all rights: ask zyx-db before reusing the design.
