PCB Design Studio USB ⚡ Schematic PCB Layout Electrical CAD Software Windows

⚡ PCB DESIGN STUDIO USB — SCHEMATIC, PCB LAYOUT & ELECTRICAL DIAGRAM SOFTWARE FOR WINDOWS. NO SUBSCRIPTIONS. INSTALLS FULLY OFFLINE.

Plug the drive into your Windows PC, run the installers, and design circuit boards, schematics and electrical diagrams — everything installs from the drive with no internet connection. PCB Design Studio brings together three free open-source tools: the KiCad 10 electronics design suite (schematic + PCB layout + 3D viewer + simulation), TinyCAD 3.0 for quick schematics and netlists, and QElectroTech 0.100 for industrial electrical and control diagrams — plus official manuals, an original quick-start guide, licenses and full source code. No license keys, no activation, no registration.

🔌 COMPLETE ELECTRONICS DESIGN TOOLKIT (KiCad 10)
- Schematic capture with hierarchical multi-sheet designs, electrical rules check (ERC)
- Huge built-in libraries: about 22,000 symbols, about 15,000 footprints and about 7,000 3D models — all included on the drive
- PCB layout editor: multi-layer boards, interactive router, design rules checking (DRC), copper zones
- Footprint editor and library manager; PCB calculator for track widths, vias, regulators and resistor color codes
- 3D board viewer with 3D models and STEP/VRML export
- Manufacturing output: Gerber, drill files, pick-and-place, IPC-2581/ODB++ — plus the GerbView Gerber viewer
- Built-in circuit simulation (ngspice) and SPICE netlists
- Board templates: Arduino shields, Raspberry Pi HATs, Nucleo, BeagleBone and more
- Imports designs from Eagle, Altium, CADSTAR, EasyEDA, PADS, gEDA and more (import — it saves in its own formats)

⚡ QUICK SCHEMATICS & NETLISTS (TinyCAD 3.0)
- 42 symbol libraries: 74TTL, CMOS 4000, op-amps, regulators, transistors, passives, connectors, relays, switches, valves, microcontrollers and more
- Create and edit your own symbols; library manager with search, filter and preview
- Wires with free/45°/90° modes, snapping, automatic junctions, buses, labels and power symbols
- Netlists for PCB layout programs: PADS-PCB, Protel and Eagle SCR formats, plus SPICE and VHDL netlists
- Bill of materials / parts lists; design rules check
- Save as PDF via Windows\' built-in \"Microsoft Print to PDF\" printer; exports PNG

🏭 INDUSTRIAL ELECTRICAL DIAGRAMS (QElectroTech 0.100)
- 8,500+ elements: 3-phase power, contactors, breakers, fuses, transformers, motors, relays, terminal blocks and cross-references
- Multi-page projects with title blocks; exports PNG/JPG/BMP/SVG/DXF and prints to PDF
- Element editor to create your own symbols

📚 MANUALS, PROJECTS & SOURCE CODE
- Official KiCad manuals (PDF), TinyCAD user manual and QElectroTech quick guide
- Example projects from all three programs to learn from
- README - START HERE (txt + pdf): install, first schematic, first board, manufacturing output
- Complete source code and license texts on the drive (GPL/LGPL; libraries CC-BY-SA 4.0)

📦 WHAT\'S INCLUDED
- USB flash drive (FAT32 — reads everywhere), everything preloaded and ready to install offline
- KiCad 10.0.7, TinyCAD 3.00.04 and QElectroTech 0.100 installers for Windows
- Official manuals and original quick-start guide
- Example/demo projects and complete symbol libraries on the drive
- Source code and license texts
- Email support for setup questions

⚠️ HARDWARE LIMITATIONS — PLEASE READ BEFORE BUYING
- Windows only — no Mac or Linux versions are included (all three programs are free to download for other systems; source code is on the drive)
- Windows 10/11 64-bit for the full suite. Only TinyCAD also runs on 32-bit Windows — KiCad and QElectroTech are 64-bit only. Not for Windows 7 or 8
- Windows-on-ARM PCs: the x64 installers should run under Windows\' emulation (not separately tested; KiCad\'s own ARM build is not on the drive)
- The KiCad and QElectroTech installers on the drive are rebuilt (unsigned): Windows SmartScreen may show \"Windows protected your PC\" once — click \"More info\", then \"Run anyway\" (explained in the guide)
- A few sample files are removed from the shipped builds for licence reasons (2 KiCad demo projects, vendor 3D models in 3 demos, 1 drawing template, 6 of QElectroTech\'s 8,500+ symbols) — no listed feature depends on them
- KiCad imports (does not export) Eagle/Altium/CADSTAR/EasyEDA/PADS/gEDA designs; TinyCAD\'s PDF output goes through Windows\' built-in PDF printer
- Big board layouts feel best with 8 GB of RAM; all libraries live on the drive, so design and manufacturing outputs work fully offline
- Sticks over 32 GB are written with a 31 GB FAT32 partition — plenty for the 1.3 GB of software and libraries

✅ FREE OPEN-SOURCE SOFTWARE
- No license key needed — install on any number of your own PCs
- Not affiliated with or endorsed by the KiCad, TinyCAD or QElectroTech projects. Free, open-source software (GPL / LGPL; libraries CC-BY-SA 4.0); the price covers the USB drive, the collection, the guide and offline installation.
