Razor 9DOF I2S Pinouts

This might be a total newbie question…

I’m trying to use the Razor IMU M0 to drive an AdaFruit I2S Amp (https://www.adafruit.com/product/3006), but I’m not sure which pins on the razor to configure the I2S library (https://github.com/arduino/ArduinoCore- … raries/I2S) to use to talk to the amp. Would it be the RX/TX pins, and one of the analogs, or the I2C (SDA/SDL) pins?

Thanks!

I don’t know for sure and someone else might be able to chime in, but I think you need D8, TX and SCL to do I2S. While those are available on the Razor, there are parts on the board connected to SCL and I don’t know if that would interfere with I2S operation or not. You might be better off with a different board than this for I2S.
