Questions
How big is the Davinci Keyboard PCB?
It measures 380.2 × 121.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Davinci Keyboard use?
235 parts, built around the ESP32-S3-WROOM-1-N8, CH340K, AZ1117CH-3.3TRG1 and FDS4935A. 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 Davinci Keyboard KiCad files?
From the koki0517/Davinci-Keyboard repository on GitHub, at the commit this page was made from: the board is Davinci-Keyboard/Davinci-Keyboard.kicad_pcb and its schematic Davinci-Keyboard/Davinci-Keyboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Davinci Keyboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask koki0517 before reusing the design.
