Feature:
1.The Breadboards is 2-Sided Peelable Adhesive Tape，Easy to Stick on the Prototype Shield，Suitable for Line Prototype Design.

2.The Breadboards Can be Spliced According to the Unit, the Structure is Clear in Color.

3.A breadboard is a solderless device that is great for building and testing new circuits. Breadboard jumpers can be easily inserted and removed.

4.Breadboards are used for temporary prototypes of electronics and testing circuit designs. Most electronic components can be interconnected by inserting their leads or terminals into the holes and then connecting them with wires at the appropriate locations, saving a lot of time for your experimental circuits.
