Even a small product can include a microcontroller, sensors, power-management ICs, memory, a wireless module, and a gateway to cloud services. None of those blocks are useful in isolation. They must communicate. This guide is for engineers who want practical understanding, not only textbook definitions. You will find side-by-side protocol comparisons, real-world selection advice, interview questions, and production-focused best practices.
