This is a lightweight APP for viewing KiCAD generated schematic files in a mobile environment. No matter what questions, opinions or ideas you have, you can send an email to xjerry248@gmail.com. KiCAD Schematic Viewer is a highly professional tool developed specifically for viewing and reviewing schematic design files generated by KiCAD. The tool integrates an advanced graphical interface that allows users to deeply browse schematic designs in a single-layer view mode, supporting comprehensive analysis and verification of complex schematics. Users can view the component layout, electrical connections, and signal paths in detail, and perform interactive design verification and troubleshooting. KiCAD Schematic Viewer provides real-time zoom, pan, and rotation capabilities, enabling users to precisely locate and inspect every detail of the schematic. At the same time, the tool supports various display modes, including transparent view, high brightness display, and contrast enhancement, helping users to quickly identify and solve potential problems. You can access the Web interface of the APP directly in the browser, easily manage, upload, and download the schematic design file generated by KiCAD, and achieve cross-platform convenient and efficient file operation. KiCAD Schematic Viewer provides engineers with comprehensive support to ensure high quality, reliability, and manufacturability of schematic designs, whether at the beginning of design, mid-development, or final review before production. By using KiCAD Schematic Viewer, engineers can more efficiently perform design verification, optimization, and fault diagnosis, improving overall design efficiency and product quality. KiCAD Schematic Viewer supports the Model Context Protocol (MCP). Through this protocol, it can provide AI models with the necessary context from schematic files to enhance circuit schematic analysis. Engineers can connect KiCAD Schematic Viewer with AI - driven functions like automated design analysis and intelligent verification. This allows them to more effectively identify potential schematic design issues and improve the overall quality of their schematic designs.

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 โ€” on your phone, tablet, or directly in your browser at protoboarddesigner.com. Available on iOS and Web โ€” your projects sync seamlessly across all your devices. KEY FEATURES โ€ข WYSIWYG PCB Layout โ€” what you place on screen is exactly what gets manufactured. No surprises at the fab house. โ€ข Gerber & PDF Export โ€” send production-ready Gerber files directly to any PCB fab, or export a PDF to etch your own board at home. โ€ข KiCad Footprint Import โ€” use the built-in component library, import KiCad footprints, or add any public GitHub repository as a footprint source. โ€ข Cloud Project Sync โ€” your boards are automatically backed up and synced across iOS and Web. Start on your phone, finish in the browser โ€” or vice versa. โ€ข No Netlist Required โ€” skip the schematic step entirely and jump straight to layout. PERFECT FOR โ€ข Makers and hobbyists designing perfboard, stripboard, or custom PCB layouts โ€ข Students learning electronics and circuit board design โ€ข Arduino, Raspberry Pi, and ESP32 tinkerers moving beyond breadboards โ€ข Anyone wanting to go from idea to fabrication without weeks of learning software WHY NOT KICAD OR ALTIUM? Traditional EDA tools are powerful โ€” 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.
