How can I use Python to add a track to a specific location on my PCB in KiCad?
Adding a track to a specific location on a PCB in KiCad can be done using Python scripting. The script snippet provided shows how to create a PCB track, set its start and end points, width, layer, and net code:

```python
import pcbnew

# Initialize PCB and track
board = pcbnew.GetBoard()
track = pcbnew.PCB_TRACK(board)

# Set track properties
track.SetStart(pcbnew.wxPointMM(x1, y1))
track.SetEnd(pcbnew.wxPointMM(x2, y2))
track.SetWidth(int(thickness * pcbnew.IU_PER_MM))
track.SetLayer(layer)
track.SetNetCode(net.GetNetCode())

# Add track to the board
board.Add(track)
```

This approach is useful for precisely placing tracks in a PCB layout, crucial for routing and electrical connectivity.
