# PCB Component Detection Dataset (High-Resolution)

A YOLO-format object detection dataset for locating and classifying **electronic components on a printed circuit board** — resistors, capacitors, ICs, diodes, connectors, and more — from full high-resolution board photographs.

This dataset powers [`ParsaVictor/pcb-component-detection-yolo26`](https://huggingface.co/ParsaVictor/pcb-component-detection-yolo26), part of the [PCB Inspection Suite](https://huggingface.co/ParsaVictor/pcb-inspection-suite).

## Why high-resolution matters

A naive 640×640 export (the Roboflow default) shrinks small components like resistors down to a handful of pixels, which caps detector accuracy hard. This dataset was rebuilt from **original full-resolution board photographs** (median part size ~19px at the chosen tiling, vs ~6px in the original low-res export), with labels carefully re-mapped back onto the originals.

## Classes (13)

| Class | # instances |
|---|---|
| Resistor | 34,470 |
| Capacitor | 33,923 |
| IC | 12,015 |
| Electrolytic Capacitor | 10,508 |
| Transistor | 4,049 |
| Diode | 3,904 |
| Inductor | 3,402 |
| Connector | 2,867 |
| Marker | 2,465 |
| Other | 1,680 |
| LED | 444 |
| Switch/Button | 287 |
| Oscillator | 268 |

## Splits

| Split | Images |
|---|---|
| train | 3,005 |
| val | 321 |
| test | 292 |

Images are tiled crops from full-resolution board photographs (1024px tiles, 25% overlap) so components stay detectable at training resolution while the full board can still be reconstructed at inference time.

## Format

Standard YOLO format:
```
images/{train,val,test}/*.jpg
labels/{train,val,test}/*.txt   # class_id x_center y_center width height (normalized)
data.yaml
```

A simplified **binary "any component" variant** (single class, same images) is also used internally as a first detection stage before fine-grained classification; see the suite overview for the two-stage pipeline.

## Quick start

```python
from ultralytics import YOLO

model = YOLO("yolo26s.pt")
model.train(data="data.yaml", imgsz=1024, epochs=80)
```

```python
from huggingface_hub import snapshot_download
path = snapshot_download(repo_id="ParsaVictor/pcb-component-detection", repo_type="dataset")
```
