AB - In this paper, a circuit that can compensate for the weakness of the limiter circuit used for port protection of microcontroller training kits for learning various controllers including IoT devices is presented. To do this, the problems occurring in the existing protection circuit were analyzed, and as a result, it was confirmed that the microcontroller could not be protected against the continuous high voltage input due to the mistake of the trainee who is not yet familiar with the hardware. A new circuit is proposed to protect the microcontroller port from such continuous high voltage input. In order to prove the effect of the proposed circuit, an experimental circuit was constructed and the experiment was carried out. As a result of the experiment, it was confirmed that the microcontroller port suppresses the voltage below the allowable threshold for the overvoltage input.
