Most developers think of microcontrollers like the ESP32 as just "smaller computers," but the reality is far more interesting. Unlike Raspberry Pis or other single-board computers (SBCs), microcontrollers operate on a fundamentally different tier—running real-time operating systems (RTOS) or even bare-metal firmware, with no traditional OS in sight. This episode dives into the architectural distinctions: deterministic scheduling, memory models, boot times, and power efficiency that make microcontrollers the backbone of IoT. Learn why your smart clock or thermostat likely runs an ESP32 instead of Linux—and why that’s exactly how it should be.
