When your project moves beyond breadboards, a good PCB design tool becomes as important as your MCU choice. The market ranges from free open‑source suites to enterprise EDA platforms costing tens of thousands of dollars. Here’s a concise tour of 10 tools you’ll most often see in embedded projects.
High‑end industry tools
- Altium Designer – Full environment for schematics, layout-routing, documentation, simulation and 3D flex‑rigid design, plus strong DFM checks and migration tools. Expensive and Windows‑only, but a de‑facto standard in many companies and universities.
- Cadence OrCAD / Allegro – Focus on complex, multilayer boards. Interactive routing with constraints, BGA helpers, PSpice simulation, and combined electrical/mechanical analysis. Aimed at large, high‑reliability designs.
- PADS PCB – Industrial‑grade suite with powerful routing, DFM/DFT checks, RF options and integrated component libraries (ParQuest, Digikey).
Powerful but more accessible
- Autodesk EAGLE – Veteran PCB tool since 1988, now under Autodesk. Comes as Free, Standard and Premium; runs on macOS and Linux. Big community, lots of tutorials and libraries, though some designers find the UI clunky.
- Proteus – Combines ISIS (schematic + simulation) and ARES (PCB routing). With VSM and Visual Designer, it offers an integrated environment for Arduino and Raspberry Pi development and debugging.
- Cadstar – Now part of Zuken. Covers the full flow from schematic capture and PCB topology to mechanical integration (STEP/ACIS) and signal‑integrity checks.
Free and lighter tools
- KiCad – Fully free, open‑source EDA suite: Eeschema, Pcbnew, Gerbview,
pcbcalculatorand more. Mature enough for serious professional work and extremely popular with open‑hardware projects. - DesignSpark PCB – From RS Components. Schematic entry, auto‑placement/routing, project management, 3D viewer, Gerber and Excellon output. Good fit for hobbyists and low‑budget startups.
- Sprint‑Layout – Simple but capable prototyping tool: 2‑layer auto‑routing, through‑hole and SMD libraries, DRC and Gerber export. Common in small labs.
- Protel – Legacy predecessor of Altium Designer. Still used by some engineers who prefer the old interface or can’t justify upgrading.
Whether you’re routing a tiny STM32 sensor node or a dense ESP32 IoT board, your best tool depends on budget, team size and manufacturing requirements.
