Questions

How big is the PCRuler KiCad PCB?

It measures 314.9 × 23.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the PCRuler KiCad use?

46 parts, built around the ESP32-C6-MINI-1. 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 PCRuler KiCad KiCad files?

From the JuliCai/PCRuler repository on GitHub, at the commit this page was made from: the board is PCRuler_KiCad/PCRuler_KiCad.kicad_pcb and its schematic PCRuler_KiCad/PCRuler_KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the PCRuler KiCad design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
