Abstract

Breadboarding is useful when temporary, modifiable circuitry is needed. It allows the engineers to try out a circuit without soldering or wrapping. Different types of breadboarding aids are available today, but they are particularly directed to integrated circuit use. This article presents a breadboarding aid usable for general circuitry. The principle is to use a board and special modules that can be inserted into it (Fig. 1).

Modular Breadboarding

Breadboarding is useful when temporary, modifiable circuitry is needed. It allows the engineers to try out a circuit without soldering or wrapping. Different types of breadboarding aids are available today, but they are particularly directed to integrated circuit use. This article presents a breadboarding aid usable for general circuitry. The principle is to use a board and special modules that can be inserted into it (Fig. 1).

The board can be made of any rigid material. It is only used to hold the modules. The modules are small devices with interconnected spring contacts (Fig. 2). They are of different types. Some are for general use and can accommodate discrete components (Fig.3). Others have specialized patterns to accommodate special devices. Fig. 4 shows an example of a specialized use module, a 16-pin dual inline integrated circuit. The edge connectors allow the device mounted on the module to be combined with other devices or discrete components on other modules (Fig. 5).

Modular breadboarding has a number of advantages. Any type of electronic component may be used. The modules can be inserted anywhere on the board and in any direction, allowing the circuit to physically resemble the schematic diagram. Strap use can often be avoided when mounting a circuit.
