The Proto Screw Shield is the ultimate breakout board for a Raspberry Pi. It combines a prototyping shield with a full set of 3.5 mm screw terminal blocks. The proto shield part lets you build custom circuitry and then you can easily & securely connect wires and sensors to the terminal blocks. Great for panel mounts, buttons, sensors, enclosures, etc.

Proto Screw Shield is Pre-Assembled so that it can be directly screwed onto the thread posts. It is reliable and convenient.

The Raspberry Pi Proto Screw Shield extends all pins of the Raspberry Pi out to 3.5mm pitch screw terminals. It also has a lot of the utility provided by Raspberry Pi Proto shield, including a large prototyping space of both connected and unconnected 0.1 spaced through-holes.
