I’m using a Matrix Voice at the moment. I have an external sensor that uses I2C to communicate with its host.
I’m referring to this pinout diagram:
I can’t see where in the Matrix Voice GPIO expansion I would connect the SDA or SCL pins from my sensor. Pins 3 and 5 of the RPi don’t appear to be broken out. Is there a solution to this; i.e. a way for me to use an I2C device while the Voice is connected to the RPi?
