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.

For a similar prototyping layout that allows for semi-permanent circuits, consider the Adafruit 210-point perma-proto PCB.
