OpenPCB

Modular, open desktop PCB design suite — schematic capture, PCB layout, and a unified component library in one app.

---

OpenPCB is a desktop app that takes you from idea → schematic → PCB → fabrication-ready output, in one workspace. No separate tools for schematic capture, layout, and library management — it's all here, and it's free and open.

Status: pre-1.0, active development. Schematic capture and component library are stable; PCB layout is partially shipped (trace routing, vias, layer switching, live DRC, ratsnest).

Download

Grab the latest build from Releases:

Platform	File
macOS	.dmg / .zip (arm64 + x64)
Windows	Setup.exe
Linux	.deb / .rpm / .AppImage

Every release ships SHA256SUMS.txt — verify your download with shasum -a 256 -c SHA256SUMS.txt.

Builds are currently unsigned (beta). macOS Gatekeeper and Windows SmartScreen will warn on first launch — see Known issues below and electron/README-BETA-INSTALL.md for the fix.

Highlights

• Schematic capture — symbol placement, Manhattan wire routing, net labels, junctions, net extraction, ERC scaffolding, full undo/redo.
• PCB layout — trace routing (Manhattan + 45°), via placement with layer switch, pad rendering, MST ratsnest, board outline, component placement, live DRC, IPC-2221B-aware net classes.
• Component library — symbols, footprints (IPC-7351B preset generator + drawn editor), variants, KiCad .kicad_sym / .kicad_mod import, built-in seeded components.
• Fast, modern canvas — single React Three Fiber renderer shared by every editor, smooth pan/zoom, no lag on large boards.
• AI Assistant (dev preview) — OpenAI / Ollama / LM Studio providers, read-only tools today, write-tool scaffolding behind confirm/reject.
• Cross-platform desktop — macOS (arm64/x64), Windows x64, Linux x64. Auto-update is live on Windows and Linux; macOS auto-update lands with Developer ID signing.

Screenshots

Screenshots are intentionally omitted in this repo — open the app to see the schematic editor, PCB canvas, and library palette.

(Placeholder — real screenshots/GIFs of the schematic editor, PCB canvas, and library palette should go here to help new visitors evaluate the app at a glance.)

Known issues on first launch

• Binaries in v0.1.x-beta are unsigned. macOS Gatekeeper and Windows SmartScreen will warn — see electron/README-BETA-INSTALL.md.
• Linux AppImage needs chmod +x after download.
• electron-updater auto-update is not live on macOS yet; install new versions manually there.
