In this tutorial, we will learn about the Interfacing of SSD1306 OLED Display with Raspberry Pi Pico. In a majority of the projects, we need display units for printing text and sensor values. Nowadays, one of the most commonly used displays is the Oled display.

Getting Started Raspberry Pi Pico — Pinout, Specs — Beginner Guide

Hardware Required

  • 4pins 0.96" 128×64 OLED Display Module
  • Raspberry Pi Pico
  • Breadboard
  • Connecting Wires


OLED Display

The 0.96" 128x64 OLED display module is a compact, low-cost display module that is perfect for any project that requires a small display screen.

The module is very easy to use, with only four pins required to interface with a microcontroller. The display is clear and bright, and the module is extremely thin, making it ideal for use in portable applications.

OLED Display Features

OLED (organic light-emitting diode) displays are low-power consumption output devices able to show text and images by controlling every single pixel.

The most common size is 128×64 pixels (0.96 inches), but also the 128×32 pixels (0.91 inches) is available from e-shops.

Their screens are usually mono-colour or bi-colour. The mono-colour ones are made of blue or white pixels, while the bi-colour models usually have an upper part yellow and the lower one blue.

In this tutorial, I’m going to use the bi-colour model, but this uses also the mono-colour ones.

Circuit Diagram — SSD1306 OLED Display with Raspberry Pi Pico

You can guide to the circuit connection of the Raspberry Pi Pico and OLED display module as shown below.

  • The SDA pin of the OLED Display Module is connected to the GPIO16(Pin21)
  • The SCL pin is connected to the GPIO17(Pin22).
  • The Vcc pin is connected to the 3.3v Pin of the Pico Board which is Pin36.
  • The Ground pin of the Display module is connected to the Ground pin of the Pico board which is Pin38


Installing the SSD1306.py Library

I prefer Thonny IDE for programming. The programming here is divided into two main parts:


1. SSD1306.py

2. Main.py

MicroPython SSD1306 I2C Library

This is because the OLED Display requires an SSD1306 Driver Code first. We have to write the code for the SSD1306 Driver first. After uploading the SSD1306 Code, we can then run the main.py code.

I hope you have managed to get this working and enjoy the result. You now have a tested starting point for your own projects.
