Prototyping Shield Diy Kits. Great for building your own designed Arduino Uno sheilds.
You can solder parts to the prototyping area to create your project, or use it with a small solderless breadboard to quickly test circuit ideas without having to solder.
It's got extra connections for all of the Arduino MEGA 1280 / 2560 R1 R2 R3 pins, and it's got space to mount through-hole and surface mount integrated circuits.
The Prototyping Shield makes it easy for you to design custom circuits.
It's a convenient way to make your custom circuit and Arduino into a single module.
