Design milled PCBs in your browser

QUAD is a layout tool for small double-sided PCBs cut on a CNC mill (built for the Makera Z1) — from parts to G-code, enclosure included.

Module-first library — ESP32, displays, converters, regulators and dozens of other off-the-shelf breakout modules, plus 0603/0805 and through-hole discretes. Add your own parts with the design wizard.
Practical routing — angled or curved tracks, auto-widening, and automatic wire-link jumpers where tracks must cross.
Schematic view — a real, editable schematic derived from your layout; add or remove connections and the copper follows.
Enclosure & front panel — 3D case designer with per-face materials, panel-mount parts, SVG panel drawings and OpenSCAD export.
Mill-ready output — three-tool G-code (isolation, drill, outline) with animated toolpath preview, plus BOM and SVG exports.

Your boards, sub-circuit designs and part library are stored on the server with your account — sign in from any machine on the LAN.
