• Buildroot RTLinux

The Dusun DSOM-042R can be evaluated using the DSGW-380 carrier board for gateways. However, this board is better suited for the Rockchip RK3588 version of the module and may not support advanced automotive features such as multiple cameras or extensive display interfaces. For specific automotive applications, custom carrier boards would need to be developed either by the customer or through Dusun’s ODM services.

Due to the custom nature of this design, pricing and availability details are not provided upfront. Interested customers are encouraged to contact Dusun directly to discuss their specific project requirements.
