Can I automate PCB trace routing with Python in KiCad?
Yes, you can automate PCB trace routing in KiCad using Python. The script provided automates the process of adding tracks between specific pads of different footprints. It demonstrates routing a track from 'R1' to 'D1':

```python
import pcbnew
from pcbnew import wxPoint, wxPointMM

def add_track(start, end, layer=pcbnew.F_Cu):
    board = pcbnew.GetBoard()
    track = pcbnew.PCB_TRACK(board)
    track.SetStart(start)
    track.SetEnd(end)
    track.SetWidth(int(0.25 * 1e6))
    track.SetLayer(layer)
    board.Add(track)

board = pcbnew.GetBoard()
start = board.FindFootprintByReference('R1').FindPadByNumber('1').GetCenter()
end = board.FindFootprintByReference('D1').FindPadByNumber('1').GetCenter()
offset = end.x - start.x
thru = pcbnew.wxPoint(start.x, end.y - offset)
add_track(start, thru)
add_track(thru, end)

pcbnew.Refresh()
```

This script is an efficient way to handle trace routing in PCB designs, especially when dealing with a large number of connections.
