OLED

Identify the OLED controller and interface

OLED modules offer compact text and graphic display options for compatible electronics projects. Modules with the same diagonal size can use different controller chips, resolutions and pin arrangements, so select by the full specification.

• Check the controller marking and supported library configuration.
• Compare resolution, screen colour and viewing dimensions.
• Confirm whether the module uses I2C, SPI or another interface.
• Verify supply requirements, logic levels and the exact pinout.

Browse LCD modules for other screen formats, Arduino products for compatible project platforms, and the wider display collection for alternatives. Do not assume that a four-pin and seven-pin module are wired the same way, or that a library example uses the same controller as the supplied display.
