I will design industrial rs485 modbus communication pcb

I will design custom, high-reliability RS485 and Modbus RTU communication PCBs for your industrial automation and embedded systems. Whether you need a robust interface for PLC networks, sensor data acquisition, or motor controllers, I provide production-ready hardware layouts optimized for harsh environments.

What I Offer:

RS485 Interface & Modbus RTU hardware architecture

Galvanic isolation (Optocouplers/Digital Isolators) for ground-loop prevention

TVS diodes, gas discharge tubes, and fuse protection against surges

Selectable termination resistors and bias resistor networks

Seamless MCU integration (STM32, ESP32, Arduino, PIC)

Industrial connectors (Screw terminals, RJ45, DB9)

Deliverables:

Schematic Diagrams (PDF)

PCB Layout Gerber files & NC Drill

Bill of Materials (BOM) with sourcing links

3D STEP file of the assembled board

Industry-standard design practices (DFM, EMI/EMC mitigation) followed. Message me before placing an order to discuss your exact technical requirements.
