The VITA 90 (often referred to as VNX+) standard defines a new modular, rugged small-form-factor architecture for high-performance embedded systems where SWaP constraints dominate. VITA At roughly 30 % the size of a 3U OpenVPX module, VNX+ enables advanced processors, GPUs, FPGAs and high-speed I/O to be deployed in compact airborne, ground-vehicle, unmanned and wearable systems. Military Embedded Systems
Elma’s VNX+ capability covers the full lifecycle — architecture, packaging, manufacturing, system integration and test-qualification — so you can adopt VNX+ with confidence and accelerate time to mission.
Why VNX+ matters
- Maximized performance in constrained spaces: VNX+ supports high-bandwidth fabrics, full device ecosystems and advanced I/O while maintaining a fraction of the size and weight of legacy OpenVPX platforms. Elma
- Rugged, open-standards-based ecology: With alignment to the SOSA® Consortium (Sensor Open Systems Architecture) and VITA ecosystems, VNX+ enables modularity, upgradeability and interoperability across defense and aerospace systems. Elma
- Lower SWaP, faster cycles: Smaller form-factor, reduced power budgets and streamlined enclosure designs mean lower system cost, faster integration and easier deployment into unmanned, autonomous and mobile platforms. VITA
Elma’s VNX+ Offering
Architecture & Packaging
Elma’s engineering supports VNX+ from reference backplanes through full enclosure systems. We provide chassis, backplanes and modules designed to meet VITA 90 slot profiles (for example 400-pin and 320-pin payloads) and optimized cooling and ruggedization for harsh environments. VITA
System Integration
Our team partners with customers to integrate VNX+ modules into full subsystems — including power, thermal, I/O mapping, front-panel services and chassis management. Whether it’s unmanned ground vehicles, airborne sensor pods or compact wearable C4ISR nodes, Elma bridges from module to system.
Test & Qualification
Elma’s development platforms (for example our 3-slot FlexVNX+ test chassis) enable rapid bring-up of VNX+ plug-in cards and full system validation in lab and mission-profile conditions. Elma Our manufacturing and test facilities support AS9100/ISO9001 and defense-qualified workflows — giving you a trusted partner from prototype through production.
Manufacturing & Supply Chain
In-house manufacturing combined with global supply-chain oversight ensures Elma can deliver rugged VNX+ subsystems at scale and on schedule. Our packaging and ruggedizing expertise ensures modules survive the demands of military and aerospace deployments.
Application Examples
- Compact ISR/ sensor-processing pods mounted on unmanned vehicles or ground platforms (leveraging VNX+ high-density compute in a tight envelope). VITA
- Wearable or man-portable mission computing nodes, where size, weight and power are strictly constrained.
- Autonomous ground vehicle mission-computing platforms where traditional OpenVPX form-factors are too large or power-hungry. Elma
- Mobile C4ISR systems, defensive electronics and EW subsystems where modular upgradeability and open-standards interoperability are key.
Why Choose Elma
- Proven pedigree in open-standards embedded packaging (OpenVPX, SOSA, VME, etc) means we bring trusted experience to VNX+ adoption.
- Global manufacturing and test footprint capable of defense certifications and ruggedized system delivery.
- Full-service capability from architectural consultation to integration, manufacturing and support — you get one partner across the lifecycle.
- Focus on future-proof systems: adopting VNX+ now gives you a modular, upgrade-ready platform that can evolve as device standards mature.

FAQs
VNX+ refers to the VITA 90 modular open standard for small-form-factor embedded computing, designed to deliver high-performance compute, I/O and bandwidth in space-, weight- and power-constrained (SWaP) mission systems.
VNX+ enables advanced processors, GPUs, FPGAs and high-speed I/O to be deployed in compact envelopes — typically at about 30% of the size of a 3U OpenVPX module — making it ideal for unmanned, wearable, airborne, and other compact mission systems.
VNX+ is aligned with the Sensor Open Systems Architecture (SOSA) and broader VITA open-standards ecosystems to enable modularity, interoperability, and upgradeability in defense and aerospace systems.
Elma’s experience in open-standards embedded packaging, global manufacturing footprint, integrated lifecycle services, and rugged system delivery helps customers adopt VNX+ with confidence and accelerate time to mission
VNX+ supports high-bandwidth fabrics and advanced I/O in a fraction of the size and weight of traditional modular embedded platforms like 3U OpenVPX, enabling deployment in space- and weight-critical applications.
