Questions
How big is the Openkayo PCB?
It measures 80 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Openkayo use?
82 parts, built around the TCAN332D, ESP32-S3-WROOM-1-N8, TUSB2036VF and SS56. 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 Openkayo KiCad files?
From the CapnKernel/openkayo repository on GitHub, at the commit this page was made from: the board is openkayo.kicad_pcb and its schematic hub.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Openkayo design in my own project?
Its repository states no licence, so its author keeps all rights: ask CapnKernel before reusing the design.
