MB-102 Solderless Breadboard with 830 Tie Points for Electronic Circuit Prototyping

Large Prototyping Board with 4 Power Rails for Arduino, ESP32, Raspberry Pi and STEM Electronics Projects

The MB-102 Breadboard with 830 tie points is a versatile solution for quickly building, testing and developing electronic circuits without soldering. Its expanded working area and four separate power rails make it suitable for larger electronic projects, educational experiments and prototype development.

The central working area provides 630 connection points, arranged in 63 horizontal rows and 10 columns, divided into two symmetrical groups – A–E and F–J. A central channel separates the two terminal sections and allows direct insertion of integrated circuits in standard DIP packages. This makes it easy to build electronic circuits using resistors, capacitors, diodes, transistors, sensors and other components.

For convenient power distribution, the breadboard features four power rails with a total of 200 connection points, positioned at the top and bottom. Red markings indicate positive power (+), while blue or black markings indicate negative power (-). This simplifies power connections and the integration of different electronic modules.

The internal contacts are manufactured from spring-loaded phosphor bronze with a nickel-plated finish, providing reliable electrical connections and good durability during repeated insertion and removal of wires. The housing is made of durable white ABS plastic and features clearly printed alphanumeric coordinate markings for easy circuit navigation.

The integrated side interlocking connectors allow multiple MB-102 breadboards to be connected together, making it possible to expand the working area for more complex electronic systems.

The bottom surface features self-adhesive foam backing, allowing secure attachment to workbenches, development platforms, robot chassis and electronic enclosures.
