Questions
How big is the Tutorial PCB?
It measures 84.2 × 39.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tutorial use?
25 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 Tutorial KiCad files?
From the MisguidedBadge/Keyboard_Example repository on GitHub, at the commit this page was made from: the board is Tut1/Tutorial/Tutorial.kicad_pcb and its schematic Tut1/Tutorial/Tutorial.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tutorial design in my own project?
Its repository states no licence, so its author keeps all rights: ask MisguidedBadge before reusing the design.
