Construction of Economical Portable Electronic Technology Comprehensive Laboratory

Most of the portable electronic technology laboratory equipment on the market are expensive and cannot be equipped to every student. This paper puts forward a design scheme of an economical portable electronic technology comprehensive laboratory, which is cost-effective and easy to carry. It can independently carry out basic experiments of electronic technology, and also carry out software and hardware combined, analog and digital combined, and single-chip microcomputer analog and digital combined and other comprehensive experiments of electronic technology. The high-level, challenge rating and innovation requirements of the experiments are significantly improved. It can not only solve the experimental problems of electronic technology courses, but also further expand the scope of students’ innovative experiments, further mobilize students’ learning enthusiasm, improve practical ability, and close the combination of theoretical learning and practice.
