Hey there,

Hoping someone could point me to a PCB that is using a Blackpill and a ST7789V OLED display. I have the above and am not 100% on which pins to wire up. GND is obvious. VCC I’m pointing to 3.3V, then there is:

  • CS
  • DC
  • Reset
  • SDA
  • SCL

The smaller screens only have SDA & SCL. Can anyone confirm whether the others are optional, mandatory, whether there are specific/preferred pins?

I’m feeling a little lost at the moment, so hoping for some guidance.

FYI this is the specific display: here

    So basically ‘don’t worry about it, just put any pin to any pin and manage it through QMK?’
