It has extended RPI Connector to Arduino PIN, which will facilitate connections to all kinds of arduino shields. Meanwhile, two groups of electronic brick interfaces are equipped on the add-on, which are free to be connected to various electronic bricks.

Overview
Compared to Arduino, it's hard to find the shields and electronic brick customized for Raspberry Pi. This Arduino Shield Add-on has extended RPI Connector to Arduino PIN, which will facilitate connections to all kinds of arduino shields. Meanwhile, two groups of electronic brick interfaces are equipped on the add-on, which are free to be connected to various electronic bricks.

V2.0 extends all pins of Raspberry Pi 2 Model B 2*20 pin connector out to 3.5mm pitch screw terminals.It is equipped with two groups of electronic brick interfaces.
