ckochandClaude Opus 5.5 1400cc8afd Controller board: ESP32 + 2x StepStick carrier (v0.4), FluidNC config
- 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.

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
Surface finish HASL lead-free (or ENIG)
Via process Tenting vias
Finished copper 1 oz
Product No. Specify a location (the back of the board has a "WayWayWay" marker for it)

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.
