To All,
I hope someone can help me. I am looking to purchase the ADAFRUIT 326 description: Graphic LCD Display Module White OLED - Passive Matrix I²C, SPI 0.96" (24.38mm) 128 x 64. The only description on the ADAFRUIT website is a Monochrome 0.96" 128x64 OLED Graphic Display - STEMMA QT.

I don't know what the STEMMA QT is and it doesn't state if it's white or not. I sent an email to ADAFRUIT support and they told me to post my question here since they don't have a technical phone number to help customers. Please help!

STEMMA QT simply refers to some of the connectors on the board. There's a whole guide here which goes over STEMMA connectors: ... -stemma-qt
There are two flavors - STEMMA and STEMMA QT.

The STEMMA QT connector simply make connecting easier when used in conjunction with one of the purpose built wiring harnesses:
