Elbrus is a mini-ITX security-oriented motherboard for mobile/embedded usage based on the MCST Elbrus-8CB 8-core @ 1.5 GHz VLIW CPU on ELBRUS architecture.

It has 8 GB DDR4 memory, pressure sensors, tamper sensors, a water sensor, gyroscope, GPS, and much more in one single board! And most importantly - x86-64 VLIW firmware for real-time execution of x86-64 code on ELBRUS with minor performance overhead. We are also developing and manufacturing a custom fullly-copper IHS (Integrated Head Spreader) for CPU and SB (MCST KPI-2).

Open Source

Full source code for board schematics, design specifications, internal design comments, and our BSP will be published in a GitHub/GitLab open repository, and provided on a DVD that comes with the motherboard. MCST’s proprietary C/C++ compiler and bootloader will be provided only as binary, because we do not have access to the source code of this part.
