400 Holes Solder-less Breadboard Bread Board

This 3.25″ x 2.125″ solderless breadboard has four bus lines spanning the length of the board and 30 rows of pins, enough for up to four 14-pin DIP ICs or three 16-pin DIP ICs. The rows and columns of tie points are conveniently labeled, and multiple units can be connected for larger projects.
