The Prototyping Shield makes it easy for you to design custom circuits. You can solder components to create the prototyping area your project, or use it with a small breadboard (not included) to quickly test circuit ideas without solder. got extra connections for all I / O pins, and it has space to mount through-hole and surface mount integrated circuits. a convenient way to make your custom circuit and a module.
The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. three screw holes allow the shield to be attached to a surface or case. note that the distance between digital pins 7 and 8 is 160 mil (12:16 "), not an even multiple of the 100 mil distance from the other pins.
