Pre-route check passed, so I’m starting the autorouter now with the single-layer stackup in place. If the router cannot complete every connection on one copper layer, I’ll report the specific remaining airwires rather than adding vias.
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.
Wirelessly connects nets on schematic. Used to organize schematics and separate functional blocks. To wirelessly connect net portals, give them same designator. #portal
