The breadboard has 400 points that are used to plug for making connections between electronic components.

They don’t accommodate things that are too closely spaced rows of pins such as the header on the Raspberry Pi.

The Mini Breadboard consists of 400 tie points. It has 40 columns of 10 holes in which a double strip for 300 tie points are separated into two pairs by a central notch and 100 points in the power lanes.

It is a solderless and re-usable breadboard that is great for prototyping, testing, and creating add-on modules or new circuits.
