I see you have cross posted thisโ€ฆ

As far as the wiring is concerned, from the Adafruit page:
" I2C Logic pins:

  • SCK - this is also the I2C clock pin, connect to your microcontrollers I2C clock line.
  • SDI - this is also the I2C data pin, connect to your microcontrollers I2C data line.

Leave the other pins disconnected"
