MB102 830 Points Solder-less Prototype PCB Breadboard - Vayuyaan An MB102 830 Points Solderless Prototype PCB Breadboard is an invaluable tool for experimenting with circuit designs whether in the R&D or university lab. A breadboard is used to make up temporary circuits for testing or to try out an idea. No soldering is required so it is easy to change connections and replace components. 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 wires. 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.
