Abstract
This paper shows a master-slave module, which is based on a PCB board. The isomorphic circuit board can be the master or the slave through setup the configuration bits. The design can be introduced to several industrial fields, for example, the remote-based control system and the procedure control system, etc. According to the previous work of the researches, the IoT have been introduced to design the industrial equipment; nevertheless, there still have a lot of applications do not have been served. The IoT offers the information all about a system, so the equipment can be taken care anywhere anytime. In this paper, a dental system for the teeth root examining system is developed by the isomorphic master-slave module. It reduces not only the hardware complexity, but also the system development cost.
