Complete V2X system

Small 50.95 x 38.5 mm mPCIe form factor. Contains CRATON2/PLUTON2 V2X chipsets, GNSS, eHSM, 256MB DDR3 RAM, 512MB NAND, and V2Xcast® software.

Rich V2Xcast® firmware

Standard compliant V2X stacks. User friendly APIs for Service, Tx/Rx, PoTi, J2735 or ITS-G5 compliant Messages encode/decode. Application example codes including Event Detector, Traffic Signal Detector, RTK Sample Application.

Dead reckoning + 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).

Molex 7-pin backup connector

In addition to standard mPCIe connection, an additional external Molex 7-pin onboard connector can be used as a supplement to support inputs not supported directly from the host mPCIe slot.

Antenna detection & DFU

Antenna detection and diagnosis supported. Support DFU mode using command from the host platform to update the SOM firmware.

Software-defined dual-mode

Wide-ranged -40°C ~ +85°C operating temperature. Flexibly shift between DSRC-V2X or C-V2X with one V2X stack through re-flashing firmware.

Lowest 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.
