I will design rs485 modbus industrial automation controller pcb

HELLO AND WELCOME

ndustrial devices need stable communication and reliable control hardware. I develop custom RS485 and Modbus RTU PCB solutions for automation, monitoring, sensor, relay, and control applications.

I am Rapheal, an electronics and embedded systems engineer experienced in developing practical hardware around STM32, ESP32, Arduino and other microcontrollers. I can help turn your requirements into a clear schematic, well-organized PCB, and manufacturing-ready files.

What I can help with:

• RS485 communication circuits
• Modbus RTU interfaces
• Industrial controller boards
• Sensor and relay interfaces
• STM32, ESP32, and Arduino integration
• UART and other communication interfaces
• PCB layout and routing
• Component selection and BOM
• Gerber and manufacturing files
• Hardware testing and troubleshooting

I work with Altium Designer, KiCad, Eagle, and EasyEDA. My focus is on clean routing, reliable communication, practical component selection, and a PCB that is ready for production.

Send me your requirements, schematic, block diagram, or existing hardware details, and I will review the project and determine the best approach.
