Why Do We Still Need Microcontrollers?
Computers and smartphones are becoming more powerful every year. So I've been thinking about a simple question: Why do we still need small microcontrollers like Arduino, ESP8266, and ESP32? Compared with a computer, a microcontroller has very limited processing power and memory. Yet they are used everywhere in IoT and embedded systems. One reason is that most embedded applications don't need a…
Computers and smartphones continue to become more powerful with each passing year. This has led to contemplation on the relevance of microcontrollers like Arduino, ESP8266, and ESP32. Although microcontrollers possess limited processing power and memory compared to their computer counterparts, they are ubiquitous in the Internet of Things (IoT) and embedded systems.
There are several reasons for the continued use of microcontrollers. Primarily, many embedded applications do not require the power of a computer. A device might merely need to read a sensor, control a motor, switch a relay, or transmit data via Wi-Fi. These tasks are well-suited to the capabilities of microcontrollers.
Moreover, microcontrollers are compact, affordable, and consume significantly less power. Their advantages make them a practical choice for numerous embedded applications.
However, the rise of Edge AI and edge computing is making devices more capable, which raises questions about their future. Will microcontrollers evolve to become more powerful and versatile, or will they be ultimately replaced by more powerful processors in many embedded applications?
The author expresses curiosity about this evolving landscape and is eager to hear the perspectives of others engaged in IoT and embedded systems.
