Designed for Demanding Environments
Industrial automation
Develop custom PLCs, I/O systems, and real-time controllers to manage and monitor industrial processes, robotics, and motion control systems. Our designs support modularity, diagnostics, and multi-protocol connectivity.
Energy and power systems
We develop IED-class controller solutions for grid automation, substation control, smart metering, and energy storage systems. They enable secure, real-time communication across distributed assets and comply with industry-specific protocols and safety standards such as IEC 61850, IEC 60870, and DNP3.
Building automation
Design controllers for HVAC, lighting, access control, and energy management systems. With our systems, you can ensure efficient real-time control, interoperability with building protocols, and low standby power consumption.

Embedded Linux development/Embedded RT Linux dev
We develop embedded Linux-based systems for controllers that require network connectivity, user interfaces, or high computing power. Our services include kernel configuration, driver integration, and secure boot implementation.
Firmware development
We create low-level firmware/embedded RT Linux for microcontrollers and application processors/SoCs in real-time controllers and custom PLCs. In our solutions, we guarantee deterministic behaviour, hardware abstraction, and efficient use of power and memory.
RTOS development
We build control systems on real-time operating systems (RTOS) where low-latency response and task prioritisation are critical – industrial, energy, building automation, and manufacturing sectors.
Hybrid solution development
RTOS + Linux integration: Enable deterministic real-time tasks alongside complex user interfaces or network stacks.RTOS + RT Linux integration (openAMP, jailhouse): We use this approach where Linux is required but strict timing constraints apply, such as in smart grid or industrial motion controllers.

Smart Grid Controller
Our processor board for smart grid environments implements functions of relay ​protection and electricity control.​ We provided system architecture, board schematic, and PCB layout design; developed custom bootloaders; ported RTEMS RTOS as a primary RTOS and Linux as a secondary one; implemented inter-core communication between RTEMS and Linux running on different CPU cores; performed sample manufacturing and board bring-up; helped the customer set up mass production.
Key features:
- ​Freescale QorIQ SoC with PowerPC cores​
- 4 × PCI-e HOST, 1 × PCI-e HOST/Device​
- 1 × RS485 Isolation, 1 × RS422 Isolation​
- 2 × Local_BUS_IO.
Programmable Logic Controller
We developed a PCB and embedded Linux BSP for an industrial board used as a part ​ of a programmable logic controller (PLC).
Key features:

Firmware for Universal Controller
We developed universal firmware and software architecture for an industrial pump manufacturer looking to replace incompatible controllers with a single solution that enables remote system management. The new controller supports new and existing lubrication systems, including oil-air aerosol delivery, and enables control via BLE, Wi-Fi, and industrial protocols.
Key features:
- Support for PROFINET, IO-LINK, Modbus, CAN
- BLE and WiFi connectivity; smartphone app and web interface
- Based on STM32 + ESP32 running FreeRTOS
