About this Gig

Need a reliable industrial controller for factory automation, industrial IoT, or machine control?

I specialize in designing industrial-grade controllers using RS485, Modbus RTU/TCP, STM32 microcontrollers, and Ethernet communication for PLC replacement, industrial monitoring, automation systems, and smart manufacturing.

From concept to prototype, I develop robust industrial electronics featuring custom PCB design, embedded firmware, communication protocol implementation, and production-ready hardware designed for continuous 24/7 operation.

I can develop:

RS485 industrial controllers
Modbus RTU devices
Modbus TCP controllers
Industrial gateway devices
Machine automation controllers
Sensor interface modules
Industrial data acquisition systems

My expertise includes custom PCB design, STM32 firmware development, RS485 communication, Modbus RTU/TCP implementation, Ethernet networking, isolated interfaces, watchdog systems, EMC-conscious design, and industrial power management.

Whether you're building a factory automation product, industrial IoT gateway, or custom machine controller, I'll help transform your concept into a reliable prototype ready for manufacturing.
