- Consider success when export for auto-routing manually. Huge challenge expected when doing it from script.
- Work on script doing schematic design
- *Assume symbol and footprint downloaded*
- Package Using: [skidl](https://xesscorp.github.io/skidl/docs/_site/)
- Record of Tips:
- Add custom library path that contains all symbols of electrical devices needed (`NodeMCU`)
- Use attribute `footprint` to add footprint for such symbol
- footprint syntax: 'footprint= libname.pretty: foot_print_name
- footprint directory should be under the same directory where `.lib` file is.
