1660-Point Laboratory Solderless Breadboard with Metal Mounting Base

Professional Solderless Prototyping System with 3 Power Terminals for Arduino, ESP32, STM32 and Electronics Development

The 1660-point laboratory breadboard system is a professional solution for building, testing and developing complex electronic circuits without soldering. It combines two full-size breadboards, integrated power distribution rails and a sturdy metal mounting base, providing a large working area for laboratory experiments, prototyping and engineering development.

The assembly consists of two standard full-size breadboards, each featuring 630 connection points in its central prototyping area. Together, they provide 1260 central connection points, arranged in two symmetrical groups of five columns (A–E and F–J) and 63 numbered rows. The central channels allow direct installation of integrated circuits in standard DIP packages.

For convenient power distribution, the system features four double power rail sections with a total of 400 connection points. These provide multiple connection points for organising VCC, GND and other supply potentials throughout different sections of the circuit.

An additional advantage is the inclusion of three screw-type power terminals (Binding Posts) located on the left side of the base. They are available in red, black and blue/green colours and allow direct connection of an external laboratory power supply using standard banana plugs. The power can then be distributed to the appropriate breadboard rails using connecting wires.

Both breadboards are factory-mounted on a sturdy black metal base measuring 214×130mm. This provides reliable mechanical support, helps prevent unwanted movement and creates a convenient working platform for extended laboratory experiments.

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

Thanks to its large number of connection points, separate power distribution rails and direct laboratory power supply connections, this model is particularly suitable for professional laboratories, development engineers, universities, radio enthusiasts and advanced DIY users.

Note: This breadboard system is designed for low-voltage DC electronic circuits. It is not suitable for 220V AC mains voltage, high-power loads or currents exceeding the specified 2A per rail. Always observe the correct polarity when connecting a laboratory power supply and check the electrical continuity of the power rails. The three terminals do not constitute an adjustable power supply; they are connection points for an external power source and power distribution.
