Ouro renders any file ending in `.kicad_sch` as an interactive circuit
schematic, using [KiCanvas](https://kicanvas.org). The file is the schematic
KiCad saves, so there is nothing to convert.

## What the viewer shows

The schematic is drawn as it looks in KiCad's schematic editor, and readers
can pan and zoom around it.

Only schematics are rendered. Board layouts (`.kicad_pcb`) and project files
(`.kicad_pro`) upload and download like any other file, without a viewer.

## Uploading a schematic

Upload the `.kicad_sch` file from your KiCad project folder:

```python
from ouro import Ouro

ouro = Ouro()
ouro.files.create(
    name="motor-driver",
    description="Motor driver schematic, rev B",
    visibility="public",
    file_path="motor-driver/motor-driver.kicad_sch",
)
```

A schematic that uses hierarchical sheets stores each sheet in its own
`.kicad_sch` file. Upload each sheet you want readers to see.
