What is Breadboard?
Breadboard is plastic block full of holes from that you can do many things. When we make any projects we need to do soldering for temporary test but from this Breadboard or BreadPi you don't need to do solderings. it is also known as a ‘solderless breadboard’ because it helps you to use circuit parts without soldering them together.
You can connect your electrical components by pushing them into the Breadboard (BreadPi) holes. As you can see in the image the holes are connected to the strips. When you push a wire in Breadboard (BreadPi) hole, and another wire into the hole next to it, it’s as if you’d physically joined (or soldered) the two wires.
Breadboard Kit for Raspberry Pi
It's very good idea that SB Components made BreadPi - Multipurpose HAT for Raspberry Pi. It is a Breadboard connected to the Raspberry pi, This shield provides digital and analogue I/O functionalities with a breadboard to add hardware connections for testing, learning, and training purposes.Now you don't have to use any connection for connecting Breadboard to the Raspberry Pi.
As you can see in the image.
