4 in 1 combination breadboard A modular solderless breadboard that can be combined into four separate boards. This flexible design lets you create independent circuits or combine sections for larger layouts, making it suitable for a wide range of electronic projects. Materials and durability Made from environmentally friendly ABS plastic and aluminum, this breadboard is designed for reuse and longlasting use. The sturdy construction helps withstand frequent prototyping and testing. Fast, solderless prototyping Prototype and modify circuits quickly without soldering. The solderless design saves time during assembly and debugging, enabling faster iteration of ideas and testing of concepts. Wide component compatibility and connection count Works with a broad range of components, including transistors, diodes, LEDs, resistors, and capacitors. It features 4700 solderless connection points, providing ample density for typical hobbyist and learning projects. Ideal use scenarios Arduino and microcontroller projects: Split the board to organize sensors, actuators, and control logic, or connect all sections for a larger prototype. Classroom and training labs: Demonstrate circuit concepts with a reusable, modular platform that supports multiple groups and experiments. Rapid hardware prototyping and testing: Quickly assemble and rework analog and digital circuits to validate ideas before committing to PCB fabrication.
