The ribbon cable is a multiconductor, flat, and thin cable used for data transmission and communication in an electronic system. Also known as multi-wire planar cables as it contains many cable wires arranged parallel to each other on the same flat plane. It is often used when space is a factor, since they are flat and lies underneath, it consumes only less space. Ribbon cables often represented by the number of conductors and spacing between them. The spacing referred to as pitch. The common pitch for ribbon cabling is 1.27mm.
The ribbon cable connects AVR using the JTAG connector. These cable wires feature high durability and it is reusable. As a result, widely used in the internal wiring in office equipment, audio, and video machines. Ribbon cables are easy to install and use, thus it can be directly inserted into the PCB.
