AGBoard - PCBEditor is a touch-friendly PCB viewer and inspection tool for iPhone and iPad. Open Gerber, Excellon, ODB++, KiCad boards and schematics, Altium, DXF, Eagle, BoardView, netlist and placement files, then zoom, measure, edit and save — all processed locally. OPEN ANY PCB FILE • Gerber RS-274X, X2 and X3 — X3 carries components and nets on its own; X2 sets each layer's role • Gerber job files (.gbrjob): a whole export in one tap, layers identified • Excellon drill files (.drl, .tap, .nc…) • ODB++ jobs (.tgz / .tar / .zip / .gz) — panels expanded, nets included • IPC-2581 designs (.cvg / .xml): layers, pads, traces and nets in one file • AutoCAD DXF (.dxf): layers, lines, arcs, circles, polylines, blocks, text • KiCad natively (.kicad_pcb, .kicad_pro, .kicad_mod) — tracks, vias, pads, zones, silkscreen, components and nets • KiCad schematics (.kicad_sch) — symbols, wires, buses, junctions, net labels, hierarchical sheets; one net search covers schematic and board • KiCad symbol libraries (.kicad_sym) and drawing sheets (.kicad_wks) • Altium natively (.PcbDoc, .PcbLib) — copper, pours, silkscreen, outline, components and nets • Save ODB++, DXF, IPC-2581 or Gerber, or convert any board to ODB++, IPC-2581 or DXF. Untouched KiCad, Eagle, Altium and BoardView sources come back exactly; compatible edits are patched • Eagle .brd boards (XML) • Landrex BoardView .brd: outline, component envelopes, pins, test points, nets • IPC-D-356 netlists for net search • CSV / TXT / POS component placement (pick-and-place) files LAYER CONTROL • Show, hide, reorder, lock, recolor, duplicate, export layers • Realistic colors • Interactive 3D view: real thickness, copper, holes and components — flip it over MEASUREMENT & ANALYSIS • Three modes: Edges for true clearance between the nearest copper, Centers for pitch, Points for anywhere • Each reading: dX/dY, angle, midpoint, clearance, overlap • Snapping to pads, holes and the grid • Export all measurements as CSV • Board statistics: size, area, hole table by diameter, smallest drill and trace • Light DRC report (CSV) • Stencil area and aspect ratios (IPC-7525C), step zones drawn on the board, PDF/CSV report NET TRACE & SEARCH • Tap a trace or pad to light its whole net across layers, no netlist needed • In BoardView files, tap a pad to light its whole net, top and bottom • Nets from IPC-D-356 netlists, ODB++ jobs or IPC-2581 files • Search any net (GND, VCC…) and highlight all of its pads MARKUP & ANNOTATIONS • Add notes, arrows, rectangles and ellipses straight on the board • Annotations stay pinned through zoom and pan, and are saved in the project EDITING TOOLS • Move, duplicate, resize and delete shapes, with editable corner radius • Single-tap or marquee multi-selection, group transforms • Mirror, rotate, reset and panelize layers COMPONENT SEARCH • Component data from Gerber X3, KiCad, Altium, ODB++, Eagle and BoardView files • Search by reference, value or package; highlight top/bottom parts FAST WORKFLOW • Drag and drop from Files (iPad) • Open from Mail, Files or any cloud provider EXPORT & SHARE • High-resolution PNG images • Multi-page vector PDF (composite + one per layer) and AirPrint • Layer CSV reports and shareable project files PRIVATE BY DESIGN Your PCB files are opened and processed entirely on your device. AGBoard does not track you and never sells personal data. It contacts agboard-app.com only to check the installed version is current; no PCB file, account, payment or analytics identifier is sent. Includes an illustrated guide in English and French. Request an improvement or another format from Help -> Request feature. Free to download and opens five files at no charge.
