📚 Project knowledge

Point this project at a folder on the PC running the server. Design notes, requirements, guides and datasheets (.md, .txt, .pdf, .docx, code, CSV…) are given to the AI: small files go straight into its context, everything else it can search and read with tools.

Design rules

The autorouter follows these rules and DRC checks the board against them. Defaults are JLCPCB's standard 2-layer capabilities — verify current limits at jlcpcb.com/capabilities.

Routing rules

Trace widthmm Wider tracks for power / GND nets Power / GND trace widthmm Clearance (copper–copper)mm Via diametermm Via drillmm Copper to board edgemm Copper layers Neck down when the full width does not fit Autorouter effort (max time)s Allow vias on SMD pins (via-in-pad — needs filled vias, extra cost). Off: vias only beside pins, or inside large exposed pads

Fab minimums (DRC)

Min trace widthmm Min clearancemm Min via drillmm Min via diametermm Min annular ringmm Min hole-to-holemm Min edge clearancemm

Custom: close this dialog with “Draw outline”, click the corners on the PCB and click the first corner to close. The corner radius rounds every corner. Generate PCB keeps the shape; Route keeps tracks inside the outline.
