Experiment circuit board

Abstract

The invention discloses a breadboard which comprises a PCB and a power supply generation area arranged on the PCB, a signal source generation area and a control area thereof, an external module jump area, a transit area, a level indicator and a digital display area; the breadboard further comprises a comprehensive circuit design card area, and the card area is provided with a slot matrix which consists of a plurality of slots. One slot comprises a jack and a plug wire, the jack is used for accommodating materials for a hole above the plug wire and is made from an insulating material, the plug wire is made from a metal material and welded on the back face of the PCB, the plug wires in each row are connected to each other, and the plug wire rows are not connected with each other. When in use, an electronic component pin is inserted into the jack and contacted with the plug wire. The breadboard is simple, economical, practical and convenient.

Description

technical field [0001] The invention relates to an experimental circuit board, in particular to an experimental circuit board used for digital electronic technology experiments. Background technique [0002] At present, when various schools set up digital electronic technology experiments, most of them use computer simulation or physical operation. [0003] The computer simulation method is convenient, quick and easy to operate, but requires students to be proficient in the operating software, which increases the difficulty of experiment preparation and increases the burden on students. At the same time, there are differences between computer simulation and actual products, which cannot achieve the effect of physical operation. [0004] The physical operation method is simple, intuitive and easy to understand, which is conducive to improving students' hands-on ability, but this method depends on experimental equipment. At present, there are mainly two ways to prepare the e...

Problems solved by technology

At present, there are mainly two ways to prepare the experimental equipment: one is to use relevant software to design the circuit board, then go to the manufacturer to manufacture, weld, and then convert it into a product. This process requires designers to have certain experience, and beginners are very Difficult, it can only be used as a welding practice, and the effect of designing the circuit cannot be achieved; another way is to purchase the experimental equipment that has been prepared in the market and use it directly. The equipment in this way is large in size, high in cost, and capital investment Relatively large, in the process of use, students found that students copied the circuit diagram, which is not conducive to the development of creativity and the cultivation of hands-on ability, and the learning effect of students is not good. At the same time, these devices are easy to damage and difficult to maintain
