STM32 Industrial IoT Automation System

@amelectronics

Hi! I have strong experience developing STM32-based embedded systems for industrial and IoT applications. I've worked with STM32F4/F7, implementing FreeRTOS, RS-485, CAN, Ethernet, MQTT/TLS, secure bootloaders, and OTA updates. One recent project involved a multi-board automation system where I designed reliable board-to-board communication, optimized deterministic control loops, and ensured stable 24/7 operation under noisy industrial conditions. I can deliver production-ready hardware, firmware, and validation aligned with your requirements.

Hello, I have 14+ years of experience developing industrial embedded hardware and firmware, taking products from concept through production. My expertise includes STM32, Nordic, ESP32, embedded Linux, industrial communication protocols, and secure IoT connectivity. A relevant project involved designing an industrial DIN-rail controller based on an STM32 MCU with Ethernet (W5500), RS-485/Modbus, isolated power, PWM-controlled high-power LED drivers, and robust communication between multiple controllers. I was responsible for hardware architecture, schematic/PCB design, firmware development, communication stack, and production readiness. One of the key challenges was achieving reliable operation in electrically noisy industrial environments while maintaining deterministic control and communication. I have also developed secure IoT systems using MQTT/TLS, FreeRTOS, OTA firmware updates, CAN, Ethernet, SPI, I2C, UART, and cellular/GNSS connectivity. My hardware designs emphasize EMC, power integrity, isolation, manufacturability, and long-term reliability. A few questions: 1. How many STM32 boards in the network? 2. Which Ethernet protocol stack is preferred (LwIP, FreeRTOS+TCP, etc.)? 3. Is the OTA update performed via Ethernet, cellular etc.? 4. Are the cloud APIs already documented? Look forward for your reply.

Hi, I bring hands-on STM32 experience from an industrial IoT environment. At Senzmate Pvt Ltd, I worked on STM32-based acoustic monitoring systems for smart agriculture, verifying multi-protocol communication — UART, SPI, MQTT over LoRa - across boards in real field conditions with noise and intermittent connectivity. I performed signal-level validation, sensor calibration testing, and environmental stress testing. I also led an Automated Test Framework project, integrating ML models onto an ESP32-S3 and running full Hardware-in-the-Loop testing against a real I2C sensor (MAX30102), validating signal integrity in real time. At JE Scientific, I worked on FreeRTOS/Zephyr wearable hardware, debugging a critical I2C firmware logic error using in-circuit debugging — the same rigor your soak testing and timing-accuracy validation will require. Where I add the most value is validation and verification: proving timing accuracy, communication reliability (RS-485/Modbus, CAN-FD, Ethernet), and safe power-loss recovery with documented bench tests — matching your acceptance criteria. I'm also comfortable with FreeRTOS firmware and protocol-level debugging. Happy to discuss whether you need a dedicated designer or a validation engineer to pair with your team.
