LED Blinker Circuit Design
Thought for 5 sec
Here is the latest Gerber ZIP export:
show me where is 4g module
J_4G
Thought for 7 sec
The original A7672S 4G module footprint was removed from the design and replaced with a 4-pin external 4G header.
You should look for:
- Designator:
J_4G - Type: 4-pin 2.54 mm vertical header
- Location: near the right edge of Zone 2
- Pins:
VCC_5V,GND_STAR,LTE_TX,LTE_RX
So there is no large 4G module on the PCB now — the board provides
J_4G so you can connect an external 4G module by wires/header.Highlight J_4G
Export 4G wiring
Verify 4G nets

Boundary Sweep Report
Board: 180 mm x 120 mm rectangle. Flux layout coordinates are center-origin, so board edges are x = -90/+90 mm and y = -60/+60 mm. Required post-fix clearance: every component footprint/courtyard bound at least 1.5 mm from each edge, equivalent to x within [-88.5, +88.5] and y within [-58.5, +58.5].
Note: the layout summary exposes component footprint/courtyard bounds as center position, width, height, and layer. Rotation was not exposed in the structured component-bounds output; all listed components are on Top layer. Boundary checks below use the exposed footprint/courtyard bounding boxes, which include non-pad footprint extents as reported by the layout engine.
Violators Found Before Fix
No component extended outside the actual board outline x=[-90,+90], y=[-60,+60]. The recurring router anomaly appears to have been triggered by edge-clearance/courtyard proximity rather than true off-board placement.
The following components violated the requested 1.5 mm edge clearance:
Table
| Designator | Pre-fix center (mm) | Size W x H (mm) | Edge | Bound (mm) | Actual margin (mm) | Clearance shortfall (mm) | Move applied |
|---|---|---|---|---|---|---|---|
| D_TVS | (4, 54.5) | 18.96 x 8.79 | Top | y=58.895 | 1.105 | 0.395 | moved to (4, 53.5) |
| R10 | (8.86, 58.4) | 2.45 x 1.05 | Top | y=58.925 | 1.075 | 0.425 | moved to (8.86, 57.0) |
| C5 | (24, 56) | 8 x 5.5 | Top | y=58.75 | 1.25 | 0.25 | moved to (24, 55.0) |
| J3 | (25, -50) | 13.94 x 17.3 | Bottom | y=-58.65 | 1.35 | 0.15 | moved to (25, -49.8) |
| J4 | (45, -50) | 13.94 x 17.3 | Bottom | y=-58.65 | 1.35 | 0.15 | moved to (45, -49.8) |
| J5 | (-5, -50) | 13.94 x 17.3 | Bottom | y=-58.65 | 1.35 | 0.15 | moved to (-5, -49.8) |
Additional top-edge margin moves were applied after the first preflight because aggregate bounds still showed tight clearance:
Table
| Designator | Final center (mm) | Reason |
|---|---|---|
| C15 | (43, 53.5) | add top-edge margin around power/LTE cluster |
| C16 | (76, 54.5) | add top-edge margin around LTE cluster |
