Go from circuit idea to production-ready Gerber file in minutes. No netlist. No learning curve. Just open the app and start building. Protoboard Designer is a WYSIWYG PCB layout editor for makers, hobbyists, students, and anyone who finds KiCad or Altium overwhelming. Place components, route copper traces, and export your board — on your phone, tablet, or directly in your browser at protoboarddesigner.com. Available on iOS and Web — your projects sync seamlessly across all your devices. KEY FEATURES • WYSIWYG PCB Layout — what you place on screen is exactly what gets manufactured. No surprises at the fab house. • Gerber & PDF Export — send production-ready Gerber files directly to any PCB fab, or export a PDF to etch your own board at home. • KiCad Footprint Import — use the built-in component library, import KiCad footprints, or add any public GitHub repository as a footprint source. • Cloud Project Sync — your boards are automatically backed up and synced across iOS and Web. Start on your phone, finish in the browser — or vice versa. • No Netlist Required — skip the schematic step entirely and jump straight to layout. PERFECT FOR • Makers and hobbyists designing perfboard, stripboard, or custom PCB layouts • Students learning electronics and circuit board design • Arduino, Raspberry Pi, and ESP32 tinkerers moving beyond breadboards • Anyone wanting to go from idea to fabrication without weeks of learning software WHY NOT KICAD OR ALTIUM? Traditional EDA tools are powerful — but they're designed for professional engineers managing complex multi-layer boards. They take weeks to learn and are desktop-only. Protoboard Designer strips away everything you don't need for hobby and prototype work, so you can focus on building, not learning software.
