This solderless breadboard features two columns of 30 rows of pins. Comes with standard 0.1" / 2.54mm spacing and two independent power rails.
They also are modular, allowing you to connect multiple breadboards in parallel as well as series. Each breadboard also comes with a sticky back for attaching to your project box.
This is also a perfect match for our Breadboard Power Supply. You can also use our Barebones Arduino!
