Dcs

KiCad Project — Schematic & PCB

Editable source design for the Doomsday Comms System (D.C.S., SKU OS2601), board rev B.

Files

Requirements

• KiCad 7.0 or newer (the project was authored in KiCad 7).

Open dcs.kicad_pro in KiCad, then open the schematic and PCB editors from the project window.

Self-contained — no external libraries needed

This project has no dependency on any machine-specific library path. It opens complete on a fresh KiCad install:

• Footprints are embedded directly in dcs.kicad_pcb (every placed footprint carries its full pad/graphics definition), so the layout opens, edits, and fabricates without any library at all.
• Symbols are cached in dcs.kicad_sch, so the schematic opens standalone too.
• The one custom footprint library the design uses (GSC1031YB) is bundled in Misc.pretty/, and fp-lib-table references it with the project-relative ${KIPRJMOD}/Misc.pretty — so you can also place that part into new layouts.
• The per-part 3D models are bundled in 3D/; the PCB references them with the project-relative ${KIPRJMOD}/3D/…, so the 3D viewer resolves them with no setup. (For a single complete model of the assembled board, the STEP in ../04_3D_Model/ is also provided.)

All original absolute local paths were removed — nothing points outside this folder. The .kicad_prl (per-user GUI state) and editor history were not included.
