I'm trying to hook up an OLED display using I2C communication to my Arduino Pro Mini clone(with ATmega 168, 16MHz) from WAVGAT but I can't figure out where the I2C pins are on the Arduino.
Arduino – WAVGAT Arduino Pro mini I2C pins

The "official" Arduino Pro Mini pinout is:
So your I2C pins SHOULD BE at the A4 and A5 positions. There doesn't seem to be any information on the WAVGAT model. But that's common with Chinese knock-offs. You get what you get and may have to improvise.
