This OLED uses the SSD1351 driver chip, which manages the display. You can talk to the driver chip using 4-wire write-only SPI (clock, data, chip select, data/command and an optional reset pin). Included on the fully assembled breakout is the OLED display and a small boost converter (required for providing 12V to the OLED) and a microSD card holder. This design includes built-in logic level shifting so you can use it with 3-5VDC power and logic levels. Our example code shows how to read a bitmap from the uSD card and display it all via SPI.

Please note: all OLEDs have a “half life” — their brightness naturally diminishes over time, albeit over many thousands of hours. This makes them a poor choice for always-on 24/7/365 use. Best to turn off the display when inactive, or consider using a color LCD for continuously running projects.
