VTX-201

V2X DSRC Module, Autotalks V2X chipset

VTX-201 is a V2X DSRC module containing V2X communication processor, RF transceiver, and DRAM/NOR memory to serve as a DSRC sub-system. Proprietary 50-pin header with automotive-grade design, VTX-201 is designed to ensure persistent RF reliability in -40°C~+85°C and vibrational environment.

Proven DSRC RF performance, ready-to-use software development kit (SDK) running on ThreadX RTOS, and optional software porting service, VTX-201 provides the best path-to-market flexibility to migrate or port V2X stack and applications for OBU or RSU. 

Along with the unique VTX-201 modular structure design concept, companies can flexibly selected required Technology Building Block of PCB-201, HVP-201, and V2X software to enable delivery of variable total V2X systems and services of On-Board-Unit (OBU), Road-Side-Unit (RSU), and V2X sensor Fusion Applications to meet new business dynamic.



Module-structure smooths Migration

VTX-201 is a subsystem module containingcommunication processor, DSRC RF,and on-board memory.It can flexibly integrate with modular-structured carrier boards of PCB-201 and HVP-201 to serve as a V2X on-board-unit, road-side-unit, or Fusion device to meet new business dynamic.
