SOM-352 is a complete V2X function sub-system. With an embedded V2Xcast® (V2X stack and SDK) in mPCIe, its design can effortlessly embedded into any existing vehicle/industrial PC, or communication platform, and easily perform secondary software development to enable V2X or V2X-sensor fusion applications for commercial vehicles, intelligent transportation, and smart road traffic applications.

Global V2X supported, SOM-352 can flexibly shift between DSRC-V2X or C-V2X with one V2X stack (US IEEE 1609/J2735 or Europe ITS-G5 V2X protocol standard) through re-flashing firmware, reducing the cost and complexity for global deployment. Consistent V2Xcast® API preserves all the value of software add-ons for any future technology change or protocol standard update.

With embedded C-ITS or ITS-G5 or IEEE 1609 stack/SAE J2735 Messages and ready-to-use V2X service profiles, users can directly configure the profiles to compose J2735 or ITS Messages per service requirements, and develop V2X applications without the hassle of handling or setting the V2X protocol details from scratch.

Advanced GNSS functions include Dead Reckoning with integrated IMU, update rate over 20Hz GNSS and multiple concurrent constellations; these provide better positioning accuracy, time synchronization, and lane-leveled position accuracy for smoother vehicle trajectory on urban roads.

  • Complete V2X system in small 50.95 x 38.5 mm product size with standard mPCIe pin-definition, containing CRATON2/PLUTON2 V2X chipsets, GNSS, eHSM, 256MB DDR3 RAM, 512MB NAND, and V2Xcast® software.
  • A rich V2Xcast® firmware containing:
    • Standard compliant V2X stacks.
    • User friendly APIs for Service, Tx/Rx, PoTi, J2735 or ITS-G5 compliant Messages encode/code.
    • Application example codes, including Event Detector to detect remote vehicle and roadside events, Traffic Signal Detector to detect current position’s signal phase, RTK Sample Application to improve GNSS accuracy.
  • Dead Reckoning with integrated IMU, update rate over 20Hz GNSS and multiple concurrent constellations provide better positioning accuracy and time synchronization for V2X applications.
  • Secured V2X communication supports SCMS or CCMS including the V2X PKI certificate management and the private key operation on the embedded Hardware Security Module (eHSM).
  • In addition to standard mPCIe connection, an additional external Molex 7-pin onboard connector can be used as a supplement to support the inputs which is not supported directly from the host mPCIe slot.
  • Antenna detection and diagnose supported.
  • Support DFU mode using command from the host platform to update the SOM firmware.
  • Wide-ranged -40°C ~ +85°C operating temperature complies with industrial application requirements.
  • Software-defined design lets the SOM flexibly shift between DSRC-V2X or C-V2X with one V2X stack (IEEE 1609 or ITS-G5 V2X standard) through re-flashing firmware.
  • Lowest entry and total ownership cost: ready-to-be-used V2X sub-system with bundle license right to use V2Xcast® software on the hardware (per MAC address) and SDK at one fixed price, no extra license fee or royalty required.
