VNX+: Small Form Factor for Vehicle-based Applications

The new VNX+ (VITA 90) standard offers rugged, high performance for severely SWaP-constrained vehicle systems. It is ideal for systems designed to fit into small spaces. Learn how it is being implemented in next-gen vehicle electronics.

The release of the Technical Standard for SOSA® Reference Architecture, Edition 2.0, Version 2 greatly expanded its coverage of VNX+, and gives suppliers and integrators basic building blocks to develop SOSA® aligned plug-in modules and backplanes using this new form factor.

In this whitepaper, we will look at the following key points: 

  • VITA 90 and its relationship with the SOSA® Technical Standard
  • Break down the VNX+ slot profiles and protocols supported by the Standard
  • Wrap up with some thoughts about its applicability to vehicle-based systems whether they be ground, air, or sea/undersea based platforms
