- KiCad project generated by pcb/tools (design, route, schematic, fab outputs). - v0.4 fixes the v0.3 review findings: low-dropout 3.3 V regulator, OR'd 5 V supply, polyfuse, USB ESD protection, input clamps, ceramic decoupling at the drivers, A4988/DRV8825 jumper, ground stitching. DRC/ERC clean. - v0.3 (as ordered) kept in pcb/archive/v0.3. - FluidNC config.yaml for the board; rho hard limit on. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
