Overview
Arduino is a massive ecosystem, if there is a way for the Raspberry Pi GPIO interface to adapt to Arduino pinouts, it is possible to use the Pi together with vast Arduino shields and hardware/software resources. The ARPI600 is just intended for this.
What is more, the ARPI600 also support XBee modules, make it easy to add wireless feature to your great project.

Supported Pi
1. Raspberry Pi 1 Model A+
2. Raspberry Pi 1 Model B+
3. Raspberry Pi 2 Model B
4. Raspberry Pi 3 Model B
5. Raspberry Pi 3 Model B+

ARPI600 Features
1. Compatible with Arduino UNO, Leonardo, easy to connect with various Arduino shields
