Abstract: In response to the problems of low integration, poor scalability of experimental platforms, and a lack of experimental content in the experimental teaching of the Internet of Things, this paper proposes a comprehensive IoT experimental platform and teaching program based on the PDA experimental board. It introduces the construction process of the hardware and software for the comprehensive IoT platform, details the experimental tasks and the implementation process, and construction achievements. The platform features clear and intuitive experimental operations, rich experimental content, and combines theoretical knowledge with practical exercises, making it convenient for students to engage in scientific research and practical training.
