A breadboard provides unlimited freedom in laying out circuits and prototyping (the process of testing out an idea by creating a primary model). The Frey Scientific Breadboard is made of heavy aluminum black anodized construction and features a total of 830 test points/holes, where circuit components like integrated circuits (ICs) and resistors can be inserted into. Users will find 3 color coded binding posts (mostly black, green and red). Board as a whole measures 7-1/4 L x 3-3/4 W inches.
