BreadBoard

Code:EET0671

You just plug-in vertically your components in the position you want without soldering. The pro-jectboard will accept up, clock-clips, the smaller DIP's. Each unit will accept transistors, diodes, LEDS, resistors, capacitors, pots and virtually all types of components. The units are desired to use # 22-30 solid hookup wire for interconnection will plug-in ease. it could be combined with a series features a unique interlocking desired, without tools to meet changing requirements and components are reuseful.

  • External Body is made of ABS.
  • The internal interconnected clips are Nickel-Plated.
