Embedded development serves as the core support for modern smart hardware and IoT technologies, with its entire industry chain exhibiting a highly specialized division of labor from chip-level to end applications. With the advancement of technologies such as 5G and AIoT, embedded systems have permeated key areas like smart homes, industrial control, and medical electronics, forming a complete ecosystem where chip manufacturers serve as the technical source, module developers act as intermediaries, and industry product vendors represent the end terminals. This article will systematically analyze the functional characteristics of the six major business segments of the embedded industry chain and provide an in-depth interpretation of the full-process business composition of industry product developers, while also outlining the core work content of embedded developers throughout the project lifecycle, offering a panoramic business reference for practitioners.
