# 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`
