About this Gig

HELLO AND WELCOME!

Industrial sensor systems require reliable communication between field devices, controllers, and monitoring equipment. I design custom RS485 Modbus sensor interface PCBs and embedded controllers for industrial automation, data acquisition, instrumentation, IoT, and connected sensing applications.


What I will provide:

  • Custom RS485 Modbus RTU interface architecture and schematic
  • Sensor input and connector integration
  • MCU-based embedded controller design
  • RS485 transceiver, termination, biasing and protection circuitry
  • Power supply, regulation and ESD protection design
  • PCB layout with component placement and routing optimization
  • BOM, Gerber, drill files and complete design documentation


Why Clients Choose Me:

  1. Practical PCB and embedded systems engineering
  2. Strong RS485 and Modbus communication knowledge
  3. Hardware and firmware designed together
  4. Clean, scalable and production-focused PCB architecture
  5. Professional technical communication.


I can work from your sensor datasheet, Modbus register map, MCU preference, reference schematic or system requirements.
