MP3 TRIGGER I2C WIRING TO ARDUINO UNO

I thank you for all of the help that I have received.

I need to add the MP3 TRIGGER to my existing Arduino UNO.

I need to select trigger and volume settings via. I2C.

My initial I2C interconnection is MP3 TRIGGER: GND, 3.3V, SDA, SCL to ARDUINO: GND, 3.3V, A4(SDA), A5(SCL)

I this the correct I2C interconnection?

I would like to hard wire the MP3 TRIGGER into all of our ARDUINO controlled systems.

That should be the correct wiring. Have you confirmed if this has worked in a small unit test?

I have not used this interconnection. The setup came from my research for an answer to the correct wiring configuration.
