Everything comes from China products reviews site purchased in China
Arduino is an open-source platform that simplifies electronic projects. There are many options for him in China, including this riser adapter with screws.
With this adapter, all Arduino pins are accessible by connectors.
Even comes with the same default ID of the Arduino Uno.
It's nice to connect wires thicker or even very thin that don't fit well into the connector of the Arduino.
See that beyond the connector with screws you can still use the traditional connector. Below, see how everything is already connected.
A good product. Great for quick projects. I leave the link to the DealExtreme:
