Discover our (co-)design and cooperation principles

BIVROST® Lite5 STX Platform is a 5” mini-STX form factor motherboard designed to face the challenges of the AI/ML, edge computing and industry 4.0 applications. Created to take I/O capacity to a next level, maximize the potential of the unified memory architecture and provide the ability to run 24/7.


Pure compute power

The Lite5 Platform provides by default hexa-core CPUs with SMT (Hyper-Threading) technology for 12 thread processing power and up to 4.3 GHz single thread clock. Supercharged by 8th/11th generation of embedded Intel® Core processors and thermal design power set to 45W sustained load is possible at high clock frequencies without thermal throttling reaching over 110 GFLOPs or raw CPU performance.

Astonishing media processing

The Lite5 Platform was designed with fast media processing in mind. Integrated Intel UHD 630 graphics can extensively accelerate video decoding and encoding with multiple streams up to 4K@60 with a low power footprint. Unified memory lowers bandwidth requirements extending available video memory up to half-installed system memory (8GB in basic configuration) for data-intensive tasks. Selected GPU also provides GPGPU compute features like OpenCL, DirectCompute and Vulkan API support.

Unparalleled industrial standards

BIVROST® Lite5 Platform is designed and manufactured based on industry-leading Advantech production lines. It meets the requirements of 24/7 service just like any other industrial computer unit. Thermal design and industrial-grade components guarantee a long product lifespan.

The hardware platform benefits from COM Express standard. Off the shelf COM Express Basic Type 6 module from Advantech lowers the production cost of the custom-designed carrier board.

If you are interested in your own license to produce the Lite5 boards (under your own brand) or add any extra features - let's talk.

Compact form factor and CNC customisation

The Lite5 can be ordered as OEM, with a development bench table or a reference CNC milled aluminum chassis. Depending on the expansion cards selected or other requirements - it is possible to order additional changes in the chassis design. We provide CAD / CAM engineer support and a full manufacturing process.

Future proofing by design

COM Express standard future proofs BIVROST® Lite5 Platform to be forward compatible with upcoming 11-gen or newer Intel® processors and Windows 11. With additional CPU power and much faster 12th generation graphics, new SOM modules can replace current 8th gen units used for this platform without product redesign and postponing market entry.

Exclusive engineering support

A dedicated support engineer is assigned to each board. The scope of support includes: system integration (physical and operating system), performance optimization for media processing, enclosures and cooling systems, software development.

Case study: multi-cam live video processing

The challenge of this project was to create a cloud-free, multi-camera live streaming mixer with an automatic switching system based on image analysis.

Minimalist form factor is combined with high I/O performance. Key features: real-time 4K video capture, mixing, colour grading and streaming with sub 10 frames latency.

Usage of Unified Memory Architecture (UMA) allowed to achieve fast in-place data operations (zero-copy paradigm).

Usage of iGPU acceleration as a coprocessor for data processing allowed to perform not only graphical data and to relieve general CPU load.

The achieved usage of CPU routed PCIe lanes for ultra-fast I/O performance:
- Full bandwidth for 3 M.2 M-Key PCIe x4 ports simultaneously
- Full bandwidth for 4 USB 3 ports working simultaneously

Fast redundant Gigabit networking

An external M.2 neural network accelerator with 2 TOPS capability was used to boost live analysis of the processed video stream and to support the live production decision support machine.

Low noise operation


up to 48h (if there is a bare motherboard in the package) or up to 10 days (if bench table selected) of up to 30 days (if CNC milled chassis requires customization)
