ZY-204 1660 Points Solderless Breadboard is an excellent size with more than enough room for more advanced prototyping. There are two terminal strips with 1260 tie-points and 4 distribution strips with 400 tie-points. Three binding posts and a great aluminum backing plate. The breadboards accept a variety of wire sizes from 20 to 29 AWG.
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 jump wires especially convenient. This 21 cm × 12 cm solderless breadboard has enough for up to two 14- or 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 two mounting holes, and tabs allow multiple units to be connected to larger projects.
