I set the PCB up as a single-copper-layer CNC-friendly board and resized it to 50 mm × 80 mm with wider margins/clearance. I also placed the parts as requested: XIAO on the right edge, TFT header on the top edge, buttons vertically on the right, and MicroSD near the XIAO.
Open items:
- Autorouting could not continue because the account is out of ACUs.
- The board still has unrouted airwires because routing did not complete.
- After adding ACUs, the next step is to rerun routing and then DRC/airwire checks.
Suggested next steps:
- Add ACUs to continue AI routing.
- Ask me to rerun the autorouter for the 1-layer CNC board.
- If 1-layer routing cannot complete, I’ll identify the exact unrouted nets and propose CNC-friendly jumper-wire options without adding vias.
