If your board does not come with a display, you will need to obtain an SSD1306 display separately. The SSD1306 OLED displays are made in two different pin oderings. The preferred OLED displays have the following pin order: VCC-GND-SCL-SDA. They can be soldered into TTGO T-Beams directly. The OLED displays with the GND-VCC-SCL-SDA pin order need to be soldered in such a way that display does not get reverse-polarity on the power terminals.

SSD1306 OLED with VCC-GND-SCL-SDA pin order (preferred)

SSD1306 VCC-GND-SCL-SDA OLED

SSD1306 OLED with GND-VCC-SCL-SDA pin order

SSD1306-GND-VCC-SCL_SDA

In order to use this OLED display, solder the OLED board this way: SSD1306 GND-VCC-SCL-SDA OLED
