Multifunctional radio frequency identification module teaching experiment system

The utility model relates to the application and development of radio frequency identification and communication technology in the Internet of things educational system and discloses a multifunctional radio frequency identification module teaching experiment system. The system comprises a main control board, related basic experiment needed peripherals, communication modules of different frequency bands and an interface circuit. A main control chip peripheral circuit and an internal instruction are optimized by the main control board, and the interface circuits of radio frequency identification modules of a plurality of frequency bands are integrated by the main control board. The system peripherals comprise all the function interfaces born by the main control chip. At the same time, according to the experiment system, the radio frequency identification modules of different frequency bands is subjected to building block type combination, a learner conveniently carries out targeted and selective learning, the system expansibility is strong, transmitting and receiving part circuits are built by a low frequency communication module by using separation elements, and the learner can deeply understand and grasp the conversion principle between a digital quantity and an analog quantity conveniently.
