VNX+ Test Jig: The Development Platform for the VNX+ Ecosystem
When you’re developing a new VNX+ SBC, GPGPU module, or power supply for a defense or aerospace program, you need more than just the hardware. You need a reliable, flexible lab environment to bring up, validate, and rigorously test your modules before they go anywhere near a mission-critical system.
That’s exactly what the VNX+ Test Jig from Tekdense is built for. It is the purpose-built development and evaluation platform for the VITA 90 (VNX+) module ecosystem.
This blog covers what the VNX+ Test Jig is, what it’s built for, and the key capabilities that support VNX+ module development.

Designed for the VNX+ Ecosystem
1. VNX+ SBC Integration
The platform supports VNX+ Single Board Computer (SBC) modules used for embedded processing in mission-critical systems. VNX+ SBC support on the VNX+ Test Jig allows developers to:
- Integrate and test VNX+ SBC modules
- Utilize standard ATX power supplies for flexible bench-level testing
- Interface with external modules or peripherals via the PCIe expansion connector
- Configure PCIe lane routing between SBC modules using the MUX select control logic
2. AI and GPU Acceleration Support
The VNX+ Test Jig also supports VNX+ GPGPU and AI modules designed for high-performance embedded computing workloads, including edge AI processing for critical embedded and edge systems. By integrating GPU acceleration modules into the VNX+ Test Jig, engineering teams can evaluate compute-intensive workloads within a compact VNX+ architecture.
3. Industrial I/O Connectivity
The VNX+ Test Jig brings all module I/Os out to industrial-grade connectors, supporting the development and testing of VNX+ modules. This design allows developers to:
- Interface with external modules or peripherals via industrial connectors
- Simplify external system integration for VNX+ components
4. Power Supply Module Compatibility
Power validation is a critical part of rugged embedded system development. The VNX+ Test Jig supports VNX+ Power Supply modules while also offering compatibility with standard ATX power supplies. This dual-power approach gives developers flexibility during early-stage prototyping and bench-level testing, and the platform’s DC power input options align with aerospace and defense power architectures.
EMI Filtering and Signal Integrity
The VNX+ Test Jig’s support for the Helios VNX+ EMI Filter Module is an essential part of reliable VNX+ power system testing. The EMI filter acts as a protective barrier, preventing unwanted electrical noise from reaching the power supply units, helping maintain stability, signal integrity, and electromagnetic compatibility across the VNX+ system.
PCIe Accessibility for Rapid Development
The VNX+ Test Jig provides accessible PCIe connectivity for external hardware integration. The x4 PCIe expansion connector — fed by the active SBC module via the MUX select control logic — allows developers to connect additional expansion cards and test communication interfaces directly on the bench.
Thermal Evaluation and Cooling Flexibility
High-performance embedded systems often require careful thermal evaluation, especially when integrating AI acceleration and GPU modules. The VNX+ Test Jig supports an optional fan assembly for optimal airflow, helping developers assess thermal performance under sustained load before transitioning hardware into deployment.
Storage and Embedded Operating System Validation
The platform provides mSATA SSD provisioning for Operating System storage on SBC-1 and SBC-2, supporting standalone application testing directly on the bench.
Applications of the VNX+ Test Jig
| Application | Typical Module Tested |
| Defense electronics | VNX+ SBC |
| Aerospace computing systems | VNX+ GPGPU / AI |
| AI edge processing | VNX+ GPGPU |
| Industrial embedded computing | VNX+ Power Module |
| EMI/noise-sensitive power systems | Helios VNX+ EMI Filter |
Why the VNX+ Test Jig Matters for VNX+ Development
As VITA 90 standards continue gaining adoption across embedded computing industries, development platforms like the VNX+ Test Jig become increasingly important for prototyping and validation. The ability to combine VNX+ SBC modules, AI and GPGPU accelerators, power supply modules, and EMI filter modules within a single accessible environment helps engineering teams streamline development cycles and reduce integration challenges.
Conclusion
The VNX+ Test Jig provides a flexible and efficient environment for VNX+ embedded system development. With support for compute, AI, power, and EMI filtering modules, the platform enables engineers to validate VNX+ architectures before deployment into rugged operational systems.
Its modular compatibility and PCIe accessibility make it a valuable solution for organizations building defense, aerospace, and AI-enabled embedded computing platforms.
