# FAQ

### Why do I want this?

The Expander gives you extra connectivity that suppliments your main MCU(s) without the cost and size of a full board. You can also use an Expander to run devices at a different voltage than the main MCU; i.e. Noctua fans are 12V where the main MCU is 24V

### How do I get one?

Included in this repository are [Production Files](https://github.com/VoronDesign/Voron-Hardware/blob/master/Klipper_Expander/Production_Files) which you can use to order from [JLCPCB](https://jlcpcb.com/) or anywhere else you order boards from. Alternatively, on the Voron Discord you may find someone selling one preassembled boards if you post in `#flea-market`

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.siboor.com/other-products/klipper-expander/faq.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
