I will design industrial protocol bridge pcb for rs485 modbus can uart interfaces
Automotive and Industrial PCB Design Embedded Hardware and Firmware
I design custom automotive and industrial electronics for connected products and control systems. My focus includes CAN Bus and OBD II interfaces, battery monitoring boards, RS485 and Modbus communica...
About this Gig
Need to connect legacy industrial equipment to a modern controller? I design custom industrial protocol bridge PCBs that help different electronic systems communicate reliably
WHAT I CAN DESIGN
- RS485 and Modbus RTU interface boards
- CAN bus and UART communication circuits
- UART to RS485 and CAN to Modbus gateway hardware
- STM32 and ESP32 based controller boards
- PLC, sensor, meter and machine interfaces
- Schematic capture, PCB layout, BOM and Gerber files
BEYOND BASIC PCB LAYOUT
Industrial communication hardware must account for electrical noise, grounding, bus termination, connector protection and service access. Where your application requires it, I can incorporate transient protection, galvanic isolation, suitable power regulation, and practical test points into the design
BUILT AROUND YOUR SYSTEM
Whether you are upgrading legacy machinery, connecting industrial sensors, building a Modbus gateway or developing a custom controller, the design will follow your interface requirements and available hardware documentation
DELIVERABLES
Receive agreed design files, component selections and manufacturing outputs according to your package. Firmware, prototype assembly
FAQ
Can you design a custom industrial protocol bridge PCB?
Yes. I can design custom communication hardware for UART, RS485, CAN bus, and Modbus RTU applications. Share the source and destination interfaces, electrical requirements, and system diagram so I can determine the appropriate design. Copy an
Can you convert UART to RS485 or CAN to Modbus?
I can design the required interface hardware and, if included in the agreed scope, the MCU-based gateway electronics. CAN-to-Modbus conversion also requires protocol mapping and firmware; a physical interface alone does not perform this conversion.
Do you provide Gerber files, BOM and PCB manufacturing outputs?
Yes, the agreed package can include PCB manufacturing files, a bill of materials, schematic documents, and relevant design source files. Pick-and-place files, assembly drawings, and 3D outputs can be agreed upon separately.
Can you add isolation and surge protection to an RS485 PCB?
Where appropriate, I can incorporate galvanic isolation, isolated power, and suitable transient-protection components. The design depends on working voltage, grounding, cable exposure, and the electrical environment. Compliance testing is
Can you modify an existing industrial PCB?
Yes. I can review an existing RS485, CAN bus, Modbus, or controller PCB and help revise the schematic, interface circuitry, component selection, or layout. Please provide the current design files, available documentation, and the problems you want to solve
