If you want to build a portable gaming console or add interactivity to a project, take a look at this OLED display from our Troyka module series. This monochrome display can show graphics, images, text messages, and the module itself uses only two pins from the control board.

The OLED display has a high contrast with viewing angles of more than 160° and does not need a backlight. The display can be viewed from any angle without loss of quality or image distortion.

What’s Inside

The module screen is made using OLED technology with a resolution of 128 × 64. OLED (organic light-emitting diode) is a matrix of dots, where each pixel is a separate organic LED. Due to the luminous pixels, the display does not need to be illuminated, and the black color is really black and will not glow in the dark. This allows for rich and contrasting images.

The display matrix is connected via the integrated chip SSD1306, and acts as an intermediary between the screen and the microcontroller. The controller board communicates with the display via I²C interface where data is transmitted over two wires.

Custom Buttons

On the sides of the display are two user defined buttons. You can assemble a simple interface or game without buying additional modules.


There are two groups on contacts on this module:


  • Power (V) - connect to the operating voltage on the microcontroller
  • Ground (G) - connect to the ground on the microcontroller
  • Signal (S2) - pin status, button S2. If you use the button, connect to a pin on the microcontroller.


  • Data (D) - I²C bus data pin. Connect to the SDA pin on the microcontroller.
  • Clock (C) - I²C bus clock pin. Connect to the SCL pin on the microcontroller.
  • Signal (S1) - pin status, button S1. If you use the button, connect to a pin on the microcontroller.

There are several different ways to wire this module:

Troyka Shield. The most straightforward method. Connect the module to a pin group on Troyka Shield with the 3-pin jumper cable and you’re ready to interface with it from your Arduino.

Troyka Slot Shield. The best choice for quick prototyping. Using slots on the shield, you can get rid of cables. The module will be held securely in place using both pin headers.

Breadboard. For advanced use. Troyka pin headers have 0.1” spacing which is compatible with any breadboard. Simply wire the module like you would do with any IC.
