Problems solved by technology
However, the disadvantage of this invention is that, firstly, although commonly used analog circuit modules are integrated, the volume of the experimental board is increased, which is not easy to carry; secondly, although the USB interface can be used for power supply, there is only one power supply, and no Various power supplies such as ±15V, ±5V fixed power supply and adjustable power supply are usually required for analog circuit experiments. Therefore, when carrying out of the laboratory, in the absence of multiple DC power supplies, it is not convenient to use various DC power supplies that require different DC power supplies. Integrated circuit chips for innovative experiments; third, although commonly used analog circuit modules are integrated, it is not convenient to build other innovative analog experimental circuits, which is inconvenient and inflexible to use, and increases teaching costs

Embodiment Construction
[0022] The portable analog circuit experiment board that the present invention proposes, its structure is as figure 1 As shown, the following functional modules are included:
[0023] The power module is used to connect to the external +15V, -15V power supply, and transform the external +15V, -15V power supply into a fixed voltage of +5V, -5V and an adjustable voltage from 1.25V to 14V. The hole is connected to the analog circuit on the breadboard; among them, the interfaces of 8 LEDs and 4 potentiometers are respectively connected to the upper right side of the breadboard, which is convenient for experimental connection, so that +15V, -15V, +5V, -5V fixed voltage And 1.25V to 14V adjustable voltage are connected to the top and bottom of the breadboard through jacks, and the interfaces of 8 LEDs and 4 potentiometers are respectively connected to the upper right of the breadboard, which is convenient for experimental connection.
[0024] The switch is used to insert a jumper c...

Description
technical field [0001] The invention relates to a portable analog circuit experiment board, which belongs to the field of electronic devices and electronic circuits. Background technique [0002] Analog electronic technology is a compulsory course for all electrical and electronic majors in colleges and universities. This course also provides analog circuit experiments while teaching theory. Therefore, it is very important to provide students with a suitable analog circuit experiment platform for cultivating students' practical ability. [0003] At present, the existing analog circuit experiment platforms provided to students in various colleges and universities are usually experimental benches, experimental boxes or learning machines, experimental devices, etc. that are not easy to move in the laboratory. Even the portable experimental boards are mainly used for Doing experiments on fixed-function circuits is not conducive to doing innovative research experiments. [0004]...
