LIS331 compatibility

Hello colleagues,

I got an accelerometer LIS331 for my raspberrry pi, and I can read directly the data output with a single python script.

I think this is a digital (I2C/SPI) sensor that could be suitable for cayenne, but I´m not able to add this sensor as a digital one (uses +3.3V/ground/SDA and SCL pins)
Is there any extra analog/digital converter to make it run?

Thanks a lot for your collaboration.

accelerometer LIS331 for my raspberry pi is not officially supported by cayenne but you can add to cayenne using GitHub - myDevicesIoT/Cayenne-MQTT-Python: Python Library for Cayenne MQTT API
