The Arduino Uno is an open-source, microcontroller-based development board built around the ATmega328P chip, commonly used as a low-cost embedded computing platform for prototyping IoT and sensing systems. In WiFi/CSI and indoor localization research, it serves as a lightweight hardware node for interfacing sensors, coordinating wireless communication modules, and collecting or relaying environmental data without the overhead of a full computing system. Its significance lies in its accessibility, broad community support, and compatibility with a wide range of communication shields and sensors, making it a practical reference platform for IoT architecture demonstrations; related variants such as the Arduino Mega and Arduino Nano offer expanded memory or smaller form factors for more constrained deployment scenarios.
