Introduction <br> 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.<br> Product Features<br> Board Material: White ABS plastic with black legend<br> Internal Contacts Material: Phosphor bronze finished<br> Board Base: Self-Adhesive Tape<br> 830 tie points total: 200 in 2 power rails, 630 in a 30 x 10 matrix<br> 400 tie points total: 100 in 2 power rails, 300 in a 30 x 10 matrix<br> Socket Pitch: 2.54mm / 0.1""<br> Contact Type: Double leaf copper spring<br> Extension Clips: Yes (Can extend with other boards)<br> Package Includes<br> 3PCS 830 Tie-Points Breadboards<br> 2PCS 400 Tie-Points Breadboards<br>"
