Questions
How big is the Layout3 PCB?
It measures 55 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Layout3 use?
45 parts, built around the ESP32-S3-WROOM-1U-N4, MP3213DH-LF-Z, RT9080-33GJ5 and SS8050-G. 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 Layout3 KiCad files?
From the Kai-IOW/Warnowsonde repository on GitHub, at the commit this page was made from: the board is Board/Layout3.kicad_pcb and its schematic Board/Layout3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Layout3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Kai-IOW before reusing the design.
