KiCad demo: common questions
How big is the KiCad demo PCB?
The KiCad demo measures 312 × 106.7 mm, has 4 copper layers and is 1.600198 mm thick.
How many components are on the KiCad demo?
185 components, from 68 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the KiCad demo design files?
From the thisis-romar/drawing-corpus repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the KiCad demo design in my own project?
The repository has no license, so all rights stay with thisis-romar. Use it as a reference, and ask the author before reusing the design.
