A breadboard for building and displaying electronic circuits used for educational purposes comprises a panel housing, an assembly panel attached to and covering the panel housing, a plurality of contact stations located on and periodically distributed over the assembly panel such that they form a regular grid, which contact stations are electrically isolated from each other and capable of receiving electronic component blocks, a plurality of first power supply points located on and periodically distributed over the assembly panel such that they form a regular grid, which first power supply points are electrically connected to each other, and a plurality of second power supply points located on and periodically distributed over the assembly panel such that they form a regular grid, which second power supply points are electrically connected to each other and the second power supply points are electrically isolated from the first power supply points, wherein the grids formed by the contact stations, the first power supply points and the second power supply points have the same periodicity.
