| `tools/` | Python generator: `design.py` (parts, placement, nets, sourcing) → `route.py` (router, ground pour, stitching vias, board file), `sch.py` (schematic), `fab.py` (PCBWay order folder, renders, copy into this folder). `place_new.py` finds free spots for parts added in a revision |
To regenerate everything, run `python3 tools/route.py && python3 tools/sch.py && python3 tools/fab.py`. The KiCad files are built in `~/kicad/sandtable-controller` because the KiCad snap can't read inside `~/snap/`.

## Notes
- **5 V budget:** the 5 V regulator supplies 1 A. The ESP32 takes up to about 0.4 A during Wi-Fi bursts, which leaves about 0.6 A for an LED strip: roughly 10 WS2812B LEDs at full white, or more at lower brightness. On USB power alone, keep the strip off; USB gives 0.5 A in total. Use a separate 5 V supply for longer strips.
