Finding the right part for our OLED displays won’t be easy, because there is a wide range of prices, and distributors for these components cannot always be trusted. Nevertheless, we’re pretty sure that we’ll go for something like the ER-OLED0.95-2C, which includes an SSD1331 controller. The latter can be driven with this simple library, courtesy of Adafruit. We will initially build a prototype with this Adafruit OLED Breakout Board, then play with the actual component when we’re getting ready to work on the faceplate PCB. 96 × 64 colorful pixels. Sweet!
