Integrated circuits are the building blocks for control, sensing, communication and power in embedded projects. Expect microcontrollers for on-board logic and peripherals, RF transceivers and wireless SoCs for short-range networking, voltage regulators for stable supplies, and audio or motor amplifiers for actuation.
Key attributes include processing performance, peripheral and protocol compatibility, power consumption and thermal behaviour, RF sensitivity and antenna options, voltage and current handling, and package or pinout compatibility for easier integration. Reliability features such as current limiting and thermal shutdown are common. Typical uses include sensor nodes, robots, automation controllers, wireless links and audio systems.
