reduce the board size so all components can fit inside maybe I would suggest you go with 100x100

Got it — I’ll switch the board to 100 × 100 mm and redo placement for that smaller outline before routing.

I’m blocked because your account has no available ACUs, so AI execution tools are unavailable and I can’t continue routing or running final checks right now.
Accomplished so far:
  • Applied the uploaded BOM MPNs/footprint fields to the project properties as provided.
  • Changed the PCB from 200 × 200 mm to 100 × 100 mm, 4-layer stackup with Layer 2 as ground and Layer 3 as power.
  • Re-placed all 141 components on the 100 × 100 mm board with functional separation: analog inputs left, ESP32 top edge, Class-D/output stage right, power/regulators bottom/right.
  • Placement is mostly cleaned up, but 3 decoupling-loop warnings remained after the last placement pass: C14, C26, C33.
Open items:
  • Route every net.
  • Resolve remaining placement/DRC warnings.
  • Run final ERC/DRC.
  • Confirm whether the custom footprint names from the spreadsheet are accepted by manufacturing/export, since some were set exactly but reported as non-standard property values.
Suggested next steps once ACUs are available:
  1. Fix C14/C26/C33 placement warnings.
  2. Run pre-route board check.
  3. Auto-route the board.
  4. Run final ERC/DRC and clean remaining issues.
