How can I batch update all footprints from a specific library in my PCB?
To batch update all footprints from a specific library in KiCad using Python, you can use the pcbnew module. However, this task is quite advanced and requires a detailed understanding of the KiCad file structure and Python scripting. This script is a basic framework:

```python
import pcbnew

# Load the current board
board = pcbnew.GetBoard()

# Define the library to update from
library_name = 'your_library_name'

# Iterate through all footprints on the board
for footprint in board.GetFootprints():
    if footprint.GetLibName() == library_name:
        # Logic to update the footprint
        # This might involve reloading the footprint from the library

# Save the updated board
board.Save('path/to/save/your/pcb.kicad_pcb')
```

This script would need to be expanded with the specific logic for updating each footprint, which could be complex depending on the changes needed.
