SIoT Introduction This document serves as the official homepage and overview of the SIoT IoT Platform User Guide. It covers the document's scope, the basic concepts and working principles of SIoT (acting as a local area network message broker), and its unique advantages in educational scenarios, such as quick startup and a low entry barrier. It also details the supported operating systems, controller hardware (such as Unihiker, micro:bit, Arduino, and Handbit), and the default connection parameters (MQTT port 1883, Web port 8080, default credentials, etc.) required for initial setup and testing.
