ROCK 4D 的 CAN 控制器支持 CAN FD（CAN with Flexible Data-Rate），可以使用示例命令中的 `fd on` 与 `dbitrate` 配置数据段波特率。

ROCK 4D 主板**不板载 CAN 收发器**，需要外接 CAN 收发器模块；如果要使用 CAN FD 较高的数据段速率，请确认外接的收发器模块本身支持 CAN FD。

:::tip
The CAN controller on ROCK 4D supports CAN FD (CAN with Flexible Data-Rate), and you can use `fd on` and `dbitrate` in the example commands to configure the data phase bitrate.

ROCK 4D **does not have an on-board CAN transceiver**, so an external CAN transceiver module is required. If you need the higher data phase bitrates of CAN FD, make sure the external transceiver module itself supports CAN FD.
