Breadboard 400 Tie Point Interlocking Solderless
A breadboard comes in handy when you want your wiring connections organized.
This breadboard is what we usually called the full-size breadboard. The total number of pins it has is 400. 100 pins of it are for the power rails on both sides, having 50 each. The middle part where you make the connections of your components are Terminal Strips, having 300 pins. The pins are spaced by a standard of 0.1"/2.54mm so that jumper cables can sit beside each other.
It also has self-adhesive on the back for mounting, and interlocking parts so that you could have a cascaded breadboard.
