Single-chip college is the course professional practice of electronic institutions, applied and engineering foundation for a strong professional or professional elective courses. From the requirements of students capacity-building perspective, such courses are taught only the basic principles of the classroom is not enough, we must strengthen the teaching practice, to allow sufficient opportunity to practice. Among them, single-chip experimental board is a good learning tool for the students. At present, more types of experimental plate in the single-chip market. The designed board is characterized by a variety of units circuit will be reasonable together on a large printed circuit board and then constitute an organic whole. The design make use of Protel99SE software to design schematic diagram, and then packaging components, PCB map, and finally the system board. It compared to the traditional teaching has the following advantages: ⑴ The prize cheap. ⑵ Use it simple, there is as long as RS232 serial port with the PC machines will be able to carry out such experiments. ⑶ Wide features, the board basically has the interface with commonly used single-
