Specifically, it is a multifunctional electronic experimental platform. Background Technology

[0002] Multifunctional electronic experimental platforms play a vital role in various university majors. In learning electronic circuit design, these platforms allow students to master the use of relevant instruments, cultivate hands-on skills, and enhance their understanding of professional knowledge. Traditional laboratory setups, often composed of multiple single-function testing and measuring instruments, require students to move around to complete measurements and collect data due to the large size of the instruments. Different experiments require different locations, and this separation is cumbersome for projects involving multiple experiments, as there is a risk of damage due to improper operation. Laboratory opening hours are limited, and unfinished experiments must be continued in the next class. The single-function instruments in these platforms are expensive and relatively complex to operate, requiring a high level of expertise, making them less beginner-friendly for university students. Furthermore, laboratory instruments are primarily powered by mains electricity; improper operation or lack of proper grounding can damage the instruments and cause personal injury.
