300 Series Solderless Breadboards

3M™ series 300 breadboards incorporate design and fabrication to yield a circuit building system with unparalleled flexibility and reliability

Image of 3M™'s 300 Series Solderless Breadboards3M's voltage distribution system, integrated with the basic component breadboarding matrix and 5-way binding posts, provides the interface for connections from a power supply, signal generator, or other external equipment.

All models incorporate the 3M laboratory-proven, multi-tie-point terminal design for convenient, solderless, plug-in circuit building. Each terminal position contains electronically connected tie points spaced on a continuous .100" matrix to accept any component with .100" lead spacing, as well as components whose leads can be dressed to fit. The surface of the steel base is high-gloss baked enamel for protection. Rubber feet prevent sliding during benchwork.

  • Simply plug in components and interconnect with ordinary 22 gauge solid wire. Time-consuming soldering is eliminated and all components can be used again.
  • 3M jumper wires are included.
  • The sturdy metal base plate serves as a ground plane to help minimize noise and voltage spikes in today's high-speed circuits.
  • DIPS of all sizes and a wide variety of discrete components with lead diameters of up to 0.32" can be used.
  • By jumping across the center area, full length distribution buses can be created vertically.
  • Use the 5-way binding posts for easy connection to ground, power supply, or other external equipment.
  • Alpha-numeric identification along the strips allows for fast and easy layout designs and project applications. Every tie-point position on the strip can quickly be identified by a letter and number combination.
  • Number of 5-tie point terminals: 94 to 768
  • Number of binding posts: 2 to 4
  • Number of distribution buses: 2 to 12
  • Number of terminal strips: 1 to 5
  • Number of tie points (total): 610 to 5424
  • Type: Assembly (on frame)
  • Wire gauge: 22 AWG
