# Board Component

This section documents the configuration attributes for each built-in board model. Use these pages when you are writing a JSON configuration, debugging a config validation error, or looking up the default for a specific attribute.

- For how to add and configure a board component on your machine, see [Board](https://docs.viam.com/hardware/common-components/add-a-board/).
- For the methods you call on a board in code, see the [Board API reference](https://docs.viam.com/reference/apis/components/board/).
- For board models outside the built-in set, search for `board` in the [Viam registry](https://app.viam.com/registry). Each registry module’s configuration is documented in its own README on its registry page.
