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
