SunFounder Breadboards Kit 3PCS 830 Point 2PCS 400 Point Solderless Breadboards for Arduino Proto Shield Distribution Connecting Blocks5 Pack

Introduction A breadboard is a construction base for prototyping of electronics. It is used to build and test circuits quickly before finalizing any circuit design. And it has many holes into which components like ICs and resistors as well as jumper wires mentioned above can be inserted. The breadboard allows you to easily plug in and remove components. There are two types of breadboard: the one with 400 holes, the other with 830 holes in the package. They are in the same using method and internal structure although different in size.
