RSU-201E is an extended temperature V2X Roadside Unit which integrates CRATON/PLUTON DSRC sub-system onto i.MX 6/Cellular/GNSS/HSM system with embedded ETSI TC-ITS stack in an IP67 enclosure. Module-structured architecture provides high application flexibility to enable "Tomorrow's V2X RSU, Today."

Enables V2X on DSRC sub-system to offload the processing power demand of the main system through RMII connection.
2. Enables V2X Fusion application on Linux with truly scalable Freescale® i.MX6 CPU and u-blox® GNSS module with feature rich I/O ports.
3. Client-server system architecture provides a smooth software migration path to enable V2X on variable Linux main system, no impact on existing Linux software.
Enables V2X RF or wireless communication solution through on-board PCIe or I/O connectivity.
Truly scalable with variable components to achieve high flexibility to speed up V2X innovations:
- Freescale® i.MX6 DualLite scales to Dual or Quad core CPU.
- u-blox® NEO-7P upgrades to NEO-M8L or M8U.
- Removes un-needed 3G, GNSS, and HSM module or lowers DRAM/NAND Memory.
- Enables LTE and Wi-Fi/Bluetooth wireless communication or 3rd party V2X RF through on-board PCIe or I/O ports.
