- 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>

|
|
**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.
