Hardware design boards

KiCad board designs made with hwde, an AI PCB design skill for Claude Code that takes a board from a written brief to a JLCPCB order. Each folder is one board's whole workspace: the brief, research notes, architecture, parts choices, the KiCad project, routing work, review reports, logs, and the fab package.

Every board has a part number of the form PCB-NNNN-R: four digits for the product, then a revision letter. register.yaml lists them.
