GLSM-01 Digital circuit and analog circuit comprehensive experiment box

Ⅰ、Equipment Overview

GLSM-01 Digital circuit and analog circuit comprehensive experiment box is mainly used for digital circuit and analog circuit experiments in electronics. It adopts a modular structure, and each module is independent of each other. Through the combination of different components in each component area, a variety of experimental circuits can be formed. The front of the experimental template is printed with a circuit diagram, and the back is equipped with devices. Each point to be tested in the experimental circuit is equipped with a test hole. It is easy to use, reliable in contact, long in life and high in efficiency. The main experimental unit is completed with matching experimental modules. Experimental expansion modules can be selected according to different needs to complete related experimental content, which can meet the needs of course experimental teaching.
