Abstract: The embedded experiment always uses outsourcing experiment box in colleges and universities.It has high cost,and the experimental project was single.It doesn’t conducive to the late update and maintenance.In this paper,a building modular structure was proposed to develop the experimental board based on STM32F103ZCT6.On the basis of the motherboard,through expanding related hardware modules,it can realize many instrumentation and industrial control prototype devices.Compared with the traditional experimental equipment,this experimental board includes designing ideas,it is more conducive to train students’ practical ability and innovation ability.At the same time,this experimental board was easy to update according to the embedded system industry development.It greatly reduced the investment cost,and was more suitable for the need of the colleges and university development.
