400 Tie-Point Solderless Breadboard

Build and test electronic circuits quickly with this 400 Tie-Point Solderless Breadboard, a practical half-size prototyping board for labs, classrooms, DIY projects, and embedded electronics development. It lets you insert jumper wires, resistors, LEDs, sensors, transistors, DIP ICs, and module pins directly into spring contact holes, so circuits can be assembled and modified without soldering or PCB fabrication. The board provides 400 total tie points with standard 2.54 mm / 0.1 inch spacing, making it compatible with common male jumper wires and through-hole electronic components. The central separation groove is designed for placing DIP integrated circuits across the middle, while the surrounding terminal strips allow easy signal routing. Power bus lanes are provided for distributing positive and ground supply lines across the prototype, helping keep Arduino, ESP, Raspberry Pi interface circuits, and sensor wiring neat and easy to debug. This 400-point breadboard is especially useful for learning electronics fundamentals such as LED circuits, voltage dividers, transistor switching, op-amp experiments, 555 timer circuits, logic IC testing, and microcontroller input/output wiring. Because it is solderless and reusable, it is also a cost-effective choice for schools, robotics clubs, engineering students, makers, and service benches where circuits are frequently changed during testing. Use it with standard 0.8 mm jumper wires or solid component leads that fit breadboard contacts. Like most solderless breadboards, it is intended for low-voltage, low-current prototyping and signal-level experiments, not for mains voltage or high-current loads. Package includes one 400 tie-point solderless breadboard. Components, jumpers, and power supply are not included.
