Differential I2C Breakout - PCA9615 to RaspberryPi

Qwiic System

Hello,

I’m trying to bring in 4 analog signals from temperature sensors to a Raspberry Pi but I only have the ethernet port available. Is it possible to pair the ADC-I2C breakout board https://www.sparkfun.com/products/15334 with the differential I2C breakout : https://www.sparkfun.com/products/14589 and then connect an ethernet cable between the differential I2C breakout and Raspberry Pi? How would the combination appear on the Raspberry Pi to read the ADC?

Thanks!

The RJ45 connector on the differential breakout board is NOT ethernet; it just uses the same connector.

Options that come to mind:

  • Connect the ADC directly to the Pi if it is close enough

  • Connect a second differential breakout board to the Pi and use a cable between the two diff breakout boards

  • Connect the ADC to something that has ethernet or wifi and have that connect to the Pi over the network
