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) +This is the SSD1306 display that matches the TTGO T-Beam boards: ![SSD1306 VCC-GND-SCL-SDA OLED](https://user-images.githubusercontent.com/3480859/184472377-ec0e1f14-72da-4e5c-957b-54164bec3400.jpg) +When the display has the proper pin order, the pins line up like this: +![SSD1306 VCC-GND-SCL-SDA OLED side view](https://user-images.githubusercontent.com/3480859/184507418-f6d14463-e922-42a2-bf9e-162d4d307d62.jpg) + # SSD1306 OLED with GND-VCC-SCL-SDA pin order +This SSD1306 display has the wrong pin order for the TTGO T-Beam boards: ![SSD1306-GND-VCC-SCL_SDA](https://user-images.githubusercontent.com/3480859/184472625-491d9220-3dba-4038-913b-c26356184e4b.PNG) In order to use this OLED display, solder the OLED board onto the main board this way:
