PRO'SKIT BREAD BOARD BX-4112N 840 Points

The Pro'sKit BX-4112N Breadboard is a professional-grade, 840-tie-point solderless breadboard designed for fast, flexible, and reliable circuit prototyping. Manufactured by Pro'sKit, a globally trusted name in electronics tools, this breadboard offers exceptional build quality, durability, and ease of use — making it the ideal choice for students, hobbyists, engineers, and educators.

The breadboard features 840 individual tie points arranged in a clear, easy-to-read layout, providing ample space for both simple beginner projects and complex multi-IC designs. The board is divided into a central component area (for ICs and components, separated by a center channel that accommodates DIP packages) and two pairs of long power distribution rails (rows) running along the top and bottom — ideal for routing VCC and GND lines across the entire board.

Each tie point is built with high-quality phosphor bronze contacts, which provide excellent electrical conductivity, flexibility, and long-term durability. The contacts grip component leads firmly while still allowing easy insertion and removal of wires, resistors, capacitors, transistors, ICs, and modules. The round-hole design is engineered for smooth plug-and-pull action, reducing wear on both the components and the breadboard itself.

The rugged ABS plastic body is wear-resistant and built to last through years of repeated use. The breadboard also includes side connectors that allow you to expand by combining multiple boards together, scaling up your prototyping space for larger projects. With clearly marked alphanumeric labels on the rows and columns, locating specific tie points and following circuit diagrams becomes effortless.

Whether you're learning electronics for the first time, building an Arduino prototype, or developing a complex sensor network, the Pro'sKit BX-4112N is the perfect platform to bring your ideas to life — no soldering required.
