Betrian needed a modular computing solution for accurate train positioning in railway transportation. Our engineering team designed a carrier board for NVIDIA Jetson modules that enables centimeter-level positioning accuracy. How did we manage to build an embedded system in a limited space that opens new possibilities for safety and efficiency in the rail industry?

What Did Betrian Need?
To support a real-time train positioning system, Betrian required a custom embedded hardware solution with high processing performance. The system had to track the position of railway vehicles with centimeter-level accuracy to improve both safety and operational efficiency.
Core Requirements:
- EN50155 compliance – Adherence to strict railway electronics standards
- High computational performance – Capable of real-time data processing
- Modular compatibility – Must work with various NVIDIA Jetson modules
- Compact design – Minimal size due to space constraints in railway equipment
- Cost-efficiency – Optimal component selection balancing performance and price
This combination of requirements posed a significant engineering challenge that demanded deep expertise in embedded hardware and experience in rugged industrial environments.
Our Solution
Based on a thorough analysis, we developed a fully customized carrier board for NVIDIA Jetson modules. We drew on our extensive experience with a focus on reliability and performance.
Optimized Hardware Design
We designed a six-layer PCB, which delivered key benefits:
- Reduced manufacturing costs by using space more efficiently
- Maintained relationships with proven suppliers
- Balanced performance with power efficiency
Flexibility and Connectivity
Our solution offers:
- NVIDIA module compatibility – Supports Jetson Nano, Xavier NX, and Origin Nano
- Rich connectivity – HDMI, Ethernet, USB-C, 2× USB 2.0, U-SIM connector, Camera CSI socket, and Quectel EM05 for 4G LTE
- Durability in harsh conditions – Includes thermal management, EMC protection, and mechanical resistance to vibration
All of this was integrated into a compact format suitable for installation in tight spaces — a common requirement in rail applications.
What Does Betrian Say About the Collaboration?
The carrier board developed by Compteq met all technical expectations and became a core component of Betrian’s positioning system. The compact form factor allows installation even in constrained spaces, while still delivering the full performance needed for real-time data processing. This combination of performance, reliability, and size unlocks new opportunities to enhance safety and streamline rail operations.
The successful project laid the groundwork for future collaboration between our companies in railway technology development.
“Compteq delivered exactly what we needed – a compact, powerful, and durable device that met all our requirements. Thanks to their solution, we can now track train sets with centimeter-level accuracy. We particularly value their ability to design hardware that operates reliably even in the demanding conditions of railway environments.”
