The Arduino prototyping shield makes it easy for you to design custom circuits for the MEGA standard Arduino pinout. It has three proto shields which are assembled, unassembled and Arduino mega. This board is used to create a project by soldering the parts to the prototyping area or a small solderless breadboard is used to test the circuit. The Mega Proto Shield Rev3 (PCB) comes with extra connections for all the Arduino I/O pins and provides space to mount through-hole and surface mounts integrated circuits. The Arduino. org shields are boards that can be plugged on top of the Arduino PCB, extending its capabilities. The different shields follow the same philosophy as the original toolkit. These Arduino Shields are easy to mount.
