UMK-352 Information Sheet

UMK-352 carrier board with SOM-352 module, connected to a PC host through USB Type-C

Streamline V2X development and system validation before deployment

UMK-352 combines the SOM-352 V2X module with the UMK-352 carrier board as a matched set, providing a ready-to-use platform for V2X application development, system testing, and validation. Powered by Unex’s V2Xcast® software stack, the kit bridges RF hardware validation and application development, enabling developers to evaluate V2X solutions for cooperative intelligent transportation systems (C-ITS) before integrating them into their target systems.

Kit overview

SOM-352 V2X module: Available in region-specific variants to match your target market’s protocol requirements
UMK-352 carrier board: Development and test platform for the SOM-352

Ready to test out of the box

The UMK Series kit supports V2X application prototyping, system validation, and antenna integration testing. Simply connect the kit to a workstation via USB Type-C to begin development and testing without additional hardware integration.

Early testing helps identify hardware and software integration issues sooner, simplifying the development process and reducing iteration time.

UMK-352 carrier board

The UMK-352 lets developers validate end-to-end V2X system operation before deployment. Its direct USB Type-C connection to a PC simplifies setup and communication.

The carrier board also facilitates diagnostics, troubleshooting, and firmware updates during development, helping streamline system integration and validation.
