GNSS/HSM Carrier Board, SL869/SLE97

PCB-201 is an automotive-grade carrier board with GNSS and Hardware Security to work with VTX-201 to provide all DSRC V2X elements in applications.

Module-structure seeds Innovation

Schematic and Gerber of PCB-201 can be provided by project to painlessly re-design carrier board for VTX-210 to create extra value and unique product identity, no impact on the existing software/services implemented on VTX-201 subsystem to seed V2X innovation.
