ESP32 Camera with OLED

flux

Short answer:
  • ERC (Electrical Rule Check): Schematic-level checks for electrical/logical issues like unconnected pins/nets, missing pull-ups, shorted or conflicting signals, power pin mistakes, or parts exceeding ratings.
  • DRC (Design Rule Check): PCB layout checks for manufacturability and spacing, such as trace width/clearance, via sizes, copper-to-edge, airwires, overlapping/floating copper, and invalid layers.
Flux specifics:
  • DRC runs continuously and is shown in the Reviews area of the editor.
  • Documentation excerpt: “Finalizing Layout: Let DRCs run automatically with each layout update, addressing physical rule checks to ensure manufacturing readiness.” Source
If you want, I can fetch your current review results and summarize what (if anything) needs fixing.

Can you run the checks is saying there's a ton of overlapping copper

flux

I checked your board’s reviews. Summary:
  • Overlapping Copper: 26 errors
  • Airwires (unrouted connections): 23 errors
  • Invalid Layer: none
  • Floating Copper: none
What Flux docs say about DRC and where to see results (verbatim): “In Flux, DRCs run in real-time, and their results can be accessed from the messages menu.” “Overlapping Traces: Triggers a DRC violation when two traces from different nets overlap each other.” Source
How to fix these quickly:
  • Overlapping copper
    • Remove or reshape any duplicate traces or short stubs that sit on top of other-net traces or pads.
    • If you drew any custom copper shapes/polygons, delete or trim the ones that bridge different nets.
    • Around dense parts (soft-latch, boost, USB-C area), pull traces back from pad edges to respect clearance.
  • Airwires
    • Route each reported pair until the airwire disappears. Prioritize power rails first (USB-C VBUS to charger IN, charger OUT to boost VIN, boost 5V to ESP32-CAM VIN, LDO 3V3 to OLED header), then I2C and buttons.
Want me to walk through the first few errors and propose exact edits for each hotspot? If yes, I’ll start with the top 3 Overlapping Copper items and outline the specific traces or shapes to move or remove.
