STM32 Industrial IoT Automation System

I am building a network of STM32-based boards that will cooperate as a single, industrial-grade automation platform. The stack must handle real-time sensor acquisition, deterministic control loops, secure cloud connectivity, and reliable board-to-board communication inside a factory environment...
