Mega Proto Shield

The Mega Proto Shield makes it easy for you to design custom circuits. You can solder parts to the prototyping area to create your project, or use it with the small solderless breadboard (included) to quickly test circuit ideas without having to solder. It's got extra connections for all of the Mega I/O pins, and it's got space to mount through-hole and surface mount integrated circuits. It's a convenient way to make your custom circuit and Mega into a single module.
