This Prototyping shield breaks out all pins on the Arduino for prototyping use in an accessible way. All pins are available with screw terminals on either side of the shield, and digital pins D2 to D13 have been made accessible via servo headers. The shield features a power select header and long-tail header plugs so it can sit nicely in an Arduino and provide additional shield compatibility. Shield also has a wide bed of prototyping vias with a set of power rails down the center.
Open Source: Yes, OSHW-compliant

None of the pins are specifically reserved by the shield: all are broken out for use in user projects.
