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 jumper wires especially convenient. This small board is compatible with the Arduino proto-shield.
> The mounting holes are spaced 37 mm apart and work with M2 screws.
> The individual breadboard can be latch on to each other to form a bigger piece of breadboard.
