270-Point Breadboard

This 3.25" x 1.75" solderless breadboard has two bus lines spanning the length of the board and 23 rows of pins, enough for up to three 14-pin DIP ICs, or two 16-pin DIP ICs. Although it is difficult to see in the pictures, the rows and columns are conveniently labeled. The board features an adhesive backing and four mounting holes, and tabs allow multiple units to be connected for larger projects.

An adhesive backing secures the 270-point breadboard to your project.

Solderless breadboards are commonly used for prototyping because they allow you to quickly build temporary circuits without soldering. Breadboards accept most through-hole parts and up to #22 wire. When you’re done or want to change your circuit, it’s easy to take your circuit apart. For best results, use solid wires when breadboarding; you’ll find pre-cut jumper wire kits and premium jumper wires especially convenient.
