Reading docs for: "How do I view and navigate DRC errors like Overlapping Copper and Airwires in Flux, and fix them? Steps to open the Reviews panel, filter specific checks, and jump to offending objects."

Reading docs for: "Where do I see DRC errors like Overlapping Copper and Airwires in Flux and how do I navigate each item to the location in the PCB layout?"

Linking components and preparing queries.

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.

Power Architecture

USB-C charge-only port (J3) feeds LiPo battery (J4, 1S via JST-PH-2), managed by BQ24012 charger (U3). Out of battery, soft-latch controller (LTC2954, U1) with pushbutton enables downstream power with load switch. Power then splits: to TPS61021A boost converter (PS1) generating 5V for ESP32-CAM VIN, and to MIC5504-3.3V LDO (U4) for OLED header (J5) and I2C pull-ups. Bulk and low-ESR 100 nF ceramic capacitors filter VBUS, battery, 5V, and 3.3V rails, ensuring stability and noise immunity for digital and analog loads.
