400 Point Solderless Breadboard

400 Point Solderless Breadboard

The half-size 400-point breadboard is the standard for sensor circuits, module testing, and Arduino/ESP32 prototyping. At 83×55mm, it fits comfortably alongside a NodeMCU or Arduino Nano without taking over your workspace.

Construction Quality

ABS plastic housing with nickel-plated spring contacts at 2.54mm pitch — the standard spacing for all DIP ICs, Arduino headers, and sensor modules. Good quality breadboards have tight contact grip; loose contacts cause intermittent connections that waste hours of debugging time.

Specifications

• Tie points: 400 (300 terminal + 100 power rail)
• Pitch: 2.54mm standard
• Dimensions: 83 × 55mm
• Power rails: 2 (one each side)
• Material: ABS with nickel-plated contacts

Pro Tip

Use with our Male-Male Jumper Wires and Male-Female Jumper Wires for clean wiring. For larger projects needing more space, consider our 830-point full-size breadboard.
