Shield - Proto PCB Rev3

The Arduino Prototyping Shield PCB makes it easy for you to design custom circuits for your next Arduino project. You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard (not included) to quickly test circuit ideas without having to solder. It's got extra connections for all of the Arduino 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 into a single module.
