- 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>

PCB settings
| Setting | Value |

| Board type | Single pieces |
| Size | 80 x 63.34 mm |
| Quantity | 5 (the minimum) |
| Layers | 2 |
| Material | FR-4, TG130-140 |
| Thickness | 1.6 mm |
| Min track / spacing | 6/6 mil |
| Min hole size | 0.3 mm |
| Solder mask / silkscreen | any colour / white |

Assembly settings (PCB Assembly quote)
| Setting | Value |
|---|---|
| Service | Turnkey (PCBWay buys the parts) |
| Assembly side | Top side only |
| Quantity | 1 or 2 (fewer than the 5 bare boards is fine) |
| Unique parts | 27 |
| SMD parts | 41 |
| BGA / QFP parts | 0 |
| Through-hole parts | 12 (10 designators; each driver socket is 2 headers) |
| Accept alternatives | Yes, for lines marked "Any brand" |
Note for PCBWay (paste into the comments box):
Please fit the female header sockets for A1 and A2 only. Do not supply the stepper driver modules; I will plug in my own. BOM lines marked "Any brand" may use any equivalent part to the description. Centroid coordinates are in mm, with the origin at the board's bottom-left corner.
When PCBWay sends their review
- Check the polarity of C1, C2 (electrolytic), D1-D3 (diodes) and D4, D5 (LEDs) against the + and bar marks in
assembly-top-v0.3.pdf. - Check that the ESP32 (U1) antenna end sits at the board edge, over the copper-free area.
- Check that pin 1 of U2, U3 and U4 is at the dot or triangle on the silkscreen.
