The Internet of Things (IoT) revolution has changed automation in various sectors, from home equipment to fac- tory processes, agriculture, and health. The backbone of this revolution is the need for low-cost, reliable, and programmable microcontrollers. The Raspberry Pi Pico, which is powered by the RP2040 microcontroller, offers a compact, low-power, and affordable board with multi-purpose I/O and dual-core capabil- ity, which is of keen interest to IoT-based automation systems. This review paper deals with the technical aspects, architectural features, and programming environments of the Raspberry Pi Pico from the IoT perspective. It focuses on its compatibility with sensors, actuators, and communication modules and evaluates its applications in real-time data processing, wireless control, and edge computing. Through case study comparisons as well as other microcontroller platforms to Pico, this paper provides a detailed insight into its contribution, advantage, and drawback in automating smart IoT systems. The paper concludes with research potential and future directions for Raspberry Pi Pico in the forthcoming generation of smart automation.
