The Proto Shield PCB r3 allows you to move your projects from the breadboard to an Arduino-compatible PCB, standing on top of the board. The Arduino MEGA Prototyping Shield PCB makes it easy for you to design custom circuits for your next Arduino MEGA project.
You can solder parts to the prototyping area to create your project, or use it with a small solder-less breadboard (not included) to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino MEGA I/O pins, and it's got space to mount through-hole and surface mount integrated circuits if you need to as well. It's a convenient way to make your custom circuit and Arduino MEGA into a single 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 “).
