0.9 Inches 128×64 OLED Display

Description

These 0.9″ OLED displays are small, only about 1″ diagonal, but very readable due to the high contrast of an OLED. This display is made of 128×64 individual white OLED pixels, each one is turned on or off by the controller chip. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast; we really like this miniature display for its crispness!

At the heart of the module is a powerful single-chip CMOS OLED driver controller – SSD1306. It can communicate with the microcontroller in multiple ways including I2C and SPI.

SPI is generally faster than I2C but requires more I/O pins. While I2C requires only two pins and can be shared with other I2C peripherals. It’s a trade-off between pins and speed. So, it really boils down to your choice.
