Fixing VIN Trace Errors

flux

The placement/routing executor has finished. I’m reconciling its changes against the live board now, then I’ll independently verify connector clearance, VIN width, redundant copper, airwires, and DRC before closing.
Worked for 3 mins 37 sec
4/4 Run DRC and resolve issues introduced by the changes

Inspect J3/J4 placement, VIN routing, and redundant-trace DRC findings

Place J3 and J4 adjacent with suitable orientation and spacing

Remove redundant copper and reroute VIN at ≥6 mm width

Run DRC and resolve issues introduced by the changes

Reading layout details for J3, J4.
Checking routing progress.
Completed 8 design checks.

Awaiting 1 background task
"PCB Verification Review" completed.

The independent review is complete; I’m reconciling its report with the live DRC results and closing the final verification task.

J3 and J4 are now adjacent and aligned, with the VIN shared feed and branches routed at 6 mm. Short 1.7 mm neckdowns remain only where required by the connector pad width.
  • Removed all 34 redundant trace/via objects
  • 0 airwires
  • 0 redundant traces
  • DRC reports no errors or warnings
  • Independent layout review passed all placement, connectivity, and routing checks

Project Specification
Project Overview
Compact PCB controller board for an addressable LED lamp installation.
Design Goal
Create a compact controller with:
  • input power stage
  • removable microcontroller socket/module interface
  • LED data/power connectors
  • required support circuitry and protection
Current Status
New project. Schematic has not been started yet.
Tentative Architecture
Because key requirements are still missing, the schematic is not yet locked. The likely architecture is:
  1. External DC power input
  2. Input protection and filtering
  3. Local logic power rail for the controller
  4. Microcontroller socket/module
  5. LED data output with level shifting if needed
  6. Power/output connectors for the LED installation
Open Requirements Needed Before Final Power Design
  1. LED type / protocol (for example WS2812B, SK6812, APA102, other)
  2. LED supply voltage (5V, 12V, 24V, or other)
  3. Maximum LED current or LED count to be controlled by this board
  4. Input power source available to the controller board
  5. Microcontroller preference / socket target (ESP32 module, XIAO, RP2040, custom MCU module, other)
  6. Whether USB programming / debugging is required on the controller board
  7. Connector preference (screw terminal, JST, pin header, other)
  8. Board size or enclosure limits
Safe Starting Assumption
If the user approves a default path, the simplest robust baseline is:
  • external 5V LED system
  • ESP32-class socketed controller module
  • separate LED power input/output connectors
  • level-shifted data output to 5V LEDs
  • local 3.3V logic rail and basic protection
Next Step
Lock the power-input and load requirements first, then perform the power budget before selecting regulator, fuse, and connectors.
