KiCad-compatible EDA: schematic, PCB, Gerber & 3D on any device.
Circuit EDA is a electronic design automation (EDA) suite for hardware engineers, electronics hobbyists, makers, students and IoT developers. It brings a modern, touch-friendly Flutter UI to the mature KiCad core, so you can open, inspect and design real PCB projects on your phone, tablet, laptop and desktop — using the very same files as KiCad. 100% KiCad file-format compatible Circuit EDA reads and writes KiCad 9.x project files losslessly, including: • Project files: .kicad_pro • Schematics: .kicad_sch (hierarchical sheets supported) • PCB layouts: .kicad_pcb (multi-layer, zones, stackup) • Symbol libraries: .kicad_sym • Footprint libraries: .kicad_mod / .pretty • Design rules: .kicad_dru • Drawing sheets: .kicad_wks • Manufacturing data: Gerber (RS-274X) and Excellon drill files You can move a project freely between Circuit EDA and desktop KiCad without conversion or data loss. All KiCad sub-apps in one place Circuit EDA mirrors the full KiCad workflow in a single, unified interface: • Project Manager — open, create and browse .kicad_pro projects with a typed file tree, recent projects and quick actions • Schematic Viewer & Editor — render full hierarchical schematics, with global search, ERC engine, BOM export and KiCad-format netlist export • PCB Viewer & Editor — multi-layer rendering with zone fill, board stackup, multi-select, auxiliary origin, hover tooltips, ruler, layer visibility presets, custom layer colors, net length report and DRC • Symbol Editor (MVP) and Footprint Editor (MVP) • Symbol and Footprint Library Browsers — including a viewer for fp-lib-table / sym-lib-table • Page Layout / Drawing Sheet Browser (PL Editor MVP) • Gerber Viewer — RS-274X + Excellon drill overlay, KiCad-compatible z-ordering • PCB Calculator — 7 KiCad-equivalent tools • Pseudo-3D Board Preview • Unified Export Hub — generate PDF, SVG, DXF, BOM, netlist, drill and pick-and-place files in one wizard • Drill chart CSV, Pick & Place CSV with auxiliary-origin and Y-mirror support • Settings — including a KiCad classic theme Cross-platform from day one The same project, the same files, on every device: • Android phones and tablets — review designs on the go, share Gerbers with your fab • iOS / iPadOS — touch-friendly viewing and lightweight editing • Windows, macOS and Linux desktop • Web Built for performance • GPU-accelerated rendering (Impeller / Skia) • BVH-based hit-testing for fast selection on dense PCBs • Engineered to keep large boards smooth while panning and zooming Engineering-grade analysis • ERC (Electrical Rules Check) engine, cross-sheet • DRC (Design Rules Check) on PCB, with rules auto-injected from .kicad_dru and .kicad_pro net classes • BOM engine, cross-sheet • Net length report, ratsnest, and global Find (Ctrl+F) for both PCB and schematic Command-line ready A built-in CLI exposes the most common KiCad-style automation: • check {drc,erc} • nets {list,ratsnest} • export {bom,svg,dxf,pdf,drill,netlist,pnp} Great for CI pipelines, batch fabrication output and headless servers.
