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.

  • \$\begingroup\$ I2C pins on the Arduino or the OLED display? if display, which one are you using? They are not all the same. \$\endgroup\$

The "official" Arduino Pro Mini pinout is:

Arduino Pro Mini Pinout from https://www.theengineeringprojects.com/2018/06/introduction-to-arduino-pro-mini.html

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.
