Frozen Placement DRC Routing
Thought for 2 mins 2 sec
I’ll continue from the current partially routed board with the new permission: small local moves are allowed in the USB/display/power areas, then I’ll route and verify DRC.
Worked for 7 mins 46 sec
The local placement pass unexpectedly nudged U3 despite the instruction not to move it, so I’m restoring that mechanical constraint first and then cleaning up the stale trace issues before routing.
Thought for 29 sec
I read the attached routing instructions, inspected the current board state, and confirmed the board still had 48 airwire DRC errors before making changes. I then ran a small-local-placement pass intended to open routing channels, but it unexpectedly nudged U3 despite the “do not move U3” constraint and introduced overlapping copper from stale routing.
Open items:
- Restore/verify U3’s intended placement and antenna keepout.
- Clean up the newly introduced overlapping copper/stale traces.
- Continue routing remaining airwires.
- Add/verify GND pours and run final DRC.
I’m blocked from continuing because the account currently has no available ACUs, so AI execution tools are unavailable right now.

Technical Construction File Notes — Mini Retro TV
Status
Draft notes for a low-volume ESP32-C3 wireless product. This is not a certification approval.
Applicable Areas
- FCC Part 15 / CE RED / UKCA: applicable because the design contains an ESP32-C3 WiFi/BLE radio module.
- Battery charger safety review: applicable because the board charges a single-cell LiPo.
Wireless Technology Summary
Table
| Module | Technology | Frequency Band | Integration Notes |
|---|---|---|---|
| ESP32-C3-MINI-1-N4 | WiFi 2.4 GHz + BLE | 2.4 GHz ISM | Use module antenna at board edge with no copper/components under antenna keepout. Enclosure materials must not detune antenna. |
Required Documentation Checklist
- Product description captured in Project Specification.
- Draft BOM and pin map captured in Schematic Notes.
- Final schematic export after review.
- Final PCB layout/Gerbers after layout.
- ESP32-C3 module certification evidence and integration conditions.
- EMC/RF test reports from accredited lab if selling commercially.
- Final user manual safety and RF statements.
RF Design Notes
- Keep ESP32-C3 antenna at an exterior board edge.
- No copper pour, traces, components, screws, battery metal, display frame, or decorative metal near the antenna keepout.
- Do not place the LiPo battery directly over the antenna area.
Open Items
- Confirm exact ESP32-C3-MINI-1-N4 certification IDs and module integration constraints before production sale.
- Revisit after PCB placement to verify antenna keepout is actually preserved.
