Questions
What parts does the Pcb layout use?
39 parts, built around the CH340C, ESP32-WROOM-32D, IRM-02-5 and S202S02F. 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 layout KiCad files?
From the johnffred/TarjetaSalidasESP32 repository on GitHub, at the commit this page was made from: the board is pcb_layout.kicad_pcb.kicad_pcb and its schematic esquematico.kicad_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pcb layout design in my own project?
Its repository states no licence, so its author keeps all rights: ask johnffred before reusing the design.
