Arduino is a massive ecosystem, if there's 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's more, the ARPI600 also support XBee modules, make it easy to add wireless feature to your great project.

Supported Pi

• Raspberry Pi 1 Model A+
• Raspberry Pi 1 Model B+
• Raspberry Pi 2 Model B
• Raspberry Pi 3 Model B
• Raspberry Pi 3 Model B+

ARPI600 Features

• Compatible with Arduino UNO, Leonardo, easy to connect with various Arduino shields
• XBee connector for connecting various XBee modules
• Sensor interface for connecting various sensors
• Onboard USB TO UART for serial port debugging, also can be configured as XBee USB adapter
• Onboard ADC, 10 bit, 38KSPS, 11 channels (6 channels for Arduino interface, 5 channels for sensors)
• Onboard RTC
