Laboratory Breadboard Platform with 4 Solderless Boards and 7 Double Power Rails

Large Solderless Prototyping System with 2 Spring Terminals for Arduino, ESP32, STM32 and Electronics Development

This expanded laboratory breadboard platform with four solderless prototyping boards is designed for building, testing and developing complex electronic circuits without soldering. Featuring a large working area, multiple power distribution rails and integrated external power terminals, it provides convenient organisation of components and electrical connections for advanced electronics projects.

The system includes 4 individual medium-sized breadboards, each offering 500 or 630 connection points depending on the specific board configuration. The boards provide sufficient space for arranging integrated circuits, resistors, capacitors, transistors, diodes, sensors and other electronic components.

For convenient power distribution, the platform features 7 double longitudinal power rails with a total of 700 connection points. These allow positive and negative supply lines to be organised and VCC and GND connections to be distributed throughout different sections of the electronic circuit.

At the right-hand side of the platform, there are two integrated two-pole spring terminal blocks with red and black release levers. They provide quick and convenient connections for stripped wires from external laboratory power supplies, transformers or batteries without soldering. This simplifies the process of supplying and distributing power to the breadboards.

An additional vertical distribution area is provided between the main boards and the terminals. It allows convenient branching and distribution of signal and power connections between different sections of the project.

All modules are mounted on a stable green base measuring 240×200mm, providing mechanical stability and an organised working surface. The breadboards are secured with screws at their corners, reducing unwanted movement during operation.

The internal contact elements are made of spring-loaded phosphor bronze with a nickel-plated finish, providing reliable electrical connections and good mechanical durability during repeated insertion and removal of jumper wires.

Thanks to its four working areas, multiple power distribution rails and integrated spring terminals, this platform is suitable for professional electronics laboratories, development engineers, repair workshops, educational institutions and advanced DIY projects.

Note: The total number of connection points in the main working areas depends on the specific configuration of the four breadboards – 500 or 630 points per board. The stated 700 connection points refer specifically to the power distribution rails. This platform is designed for low-voltage DC circuits up to 36V. It is not suitable for 220V AC mains voltage, high-power loads or currents exceeding 2A per power rail. Always check electrical continuity and correct polarity when connecting the power supply.
