Pro’skit Round Hole Bread Board (1580 Tie Points) BX-4123

The Pro'sKit BX-4123 Breadboard is a professional-grade, large-capacity solderless breadboard featuring an impressive 1580 tie points — making it one of the largest single-unit breadboards available for serious prototyping work. Manufactured by Pro'sKit , a globally recognized name in electronics tools, this breadboard delivers exceptional build quality, durability, and convenience for engineers, advanced hobbyists, university students, and electronics educators . The BX-4123 features a spacious layout divided into a large central component area (for ICs, modules, and components) separated by a center channel that accommodates standard DIP-package integrated circuits . Surrounding the component area are multiple pairs of long power distribution rails (rows) running along the top and bottom — ideal for distributing VCC, GND, and additional voltage rails across complex multi-stage circuits. A standout feature of the BX-4123 is its foldable edge plates , which can be lifted up to provide additional access during wiring or folded down flat for compact storage and use. This design improves user convenience and accelerates the prototyping workflow, especially when working on circuits with many connections. Each tie point is built with high-quality phosphor bronze contacts , providing excellent electrical conductivity, mechanical flexibility, and long-term durability . The round-hole design allows for smooth plug-and-pull insertion of wires, resistors, capacitors, ICs, and jumper wires, while keeping wear and tear to a minimum. The board's rugged ABS plastic body is wear-resistant and built to handle years of intensive use in labs, classrooms, and workshops . For even larger projects, the BX-4123 includes side connectors that allow you to combine multiple breadboards together , expanding your prototyping space without limit. With its clearly marked alphanumeric rows and columns , locating specific tie points and following circuit diagrams becomes effortless. Whether you're building a complex Arduino-based system , designing a multi-IC logic circuit , or developing an advanced sensor network , the Pro'sKit BX-4123 provides the space, reliability, and quality to bring even the most ambitious ideas to life — no soldering required .
