Improved Alternative Available! We recommend our newer 400-point breadboard with mounting holes over this product.

This 3.2" x 2.1" solderless breadboard has four bus lines spanning the length of the board and 30 rows of pins, enough for up to four 14-pin DIP ICs or three 16-pin DIP ICs. The rows and columns of tie points are conveniently labeled, and multiple units can be connected for larger projects.

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.

Two sides of the breadboard have tabs and the other two sides have compatible slots, which lets you connect multiple 400-point breadboards for more prototyping space. The breadboard also features a masked adhesive backing that can be used to secure it to your project.

For a similar prototyping layout that allows for semi-permanent circuits, consider the Adafruit 420-point Perma-Proto PCB or the flexible Adafruit 420-point Perma-Proto flex-PCB.
