Overview

About 0.96 inch OLED Display Module 128x64 SSD1306 (I2C).

The 0.96 inch OLED Display Module is the single most popular small display in the maker world, and for good reason. It packs a 128x64 pixel monochrome OLED panel driven by the SSD1306 controller onto a tiny PCB with a simple 4-pin I2C interface (GND, VCC, SCL, SDA). Because OLED pixels emit their own light, the display shows crisp white (or blue/yellow depending on the panel variant) text and graphics on a true black background with no backlight and excellent contrast, even in dim rooms.

It is the default display for Arduino, ESP8266, ESP32 and Raspberry Pi Pico projects across India because it is cheap, sips power, and only needs two signal wires. Sensor dashboards, battery voltmeters, clocks, weather stations and tiny game consoles are commonly built around this exact panel. The Adafruit SSD1306 and U8g2 libraries support it out of the box, so getting text on screen takes only a few lines of code.

At roughly Rs 175 it is an easy add-on for any beginner or hobby project. The wide 3.3V to 5V supply range means you can wire it directly to both 5V Arduino boards and 3.3V ESP32/Pico boards without a level shifter.

Key features

Why it stands out.

128x64 pixel monochrome OLED with self-emitting pixels for high contrast and deep blacks

SSD1306 driver IC with 4-pin I2C interface (VCC, GND, SCL, SDA) - only two signal wires needed

Wide 3.3V-5V operating voltage works directly with Arduino, ESP32, ESP8266 and Raspberry Pi Pico

No backlight required; very low power draw, ideal for battery projects

Supported by Adafruit_SSD1306, U8g2 and Adafruit_GFX libraries for text, graphics and bitmaps

Compact 27x27mm PCB (0.96 inch diagonal active area) fits easily on breadboards and enclosures

Buying guide

How to choose.

This is the right pick if you are a beginner or building a compact project that needs a small, sharp, low-power text/graphics display and you can drive it over I2C. If you want a physically larger screen with the same resolution, step up to the 1.3 inch SH1106 module instead.

Note the I2C address before buying: most 0.96 inch boards use 0x3C, but a few use 0x3D. If you plan to run this alongside other I2C sensors, that is fine since I2C is a shared bus. For 5V Arduino Uno/Nano and 3.3V ESP32/Pico boards you can connect it directly with no level shifter.

Pair it with an ESP32 or Arduino Nano and the U8g2 library for the smoothest experience. Buy the two-colour (yellow top / blue bottom) variant only if you specifically want a header row highlight - the pixel layout is fixed on those panels.

FAQ

Common questions.

Is this a 4-pin I2C or 7-pin SPI module?

This is the 4-pin I2C version (VCC, GND, SCL, SDA). It is the most common variant and only needs two signal wires. If you specifically need SPI, that is a different 7-pin board.

Which library should I use with Arduino?

Use the Adafruit SSD1306 library together with Adafruit GFX, or the U8g2 library. Both are free in the Arduino Library Manager. The SSD1306 driver is fully supported.

Does it work with ESP32 and Raspberry Pi Pico at 3.3V?

Yes. It operates from 3.3V to 5V, so you can wire VCC directly to the 3.3V pin of an ESP32, ESP8266 or Pico, or to 5V on an Arduino Uno/Nano, with no level shifter needed.

What is the I2C address?

Most modules use 0x3C. A small number use 0x3D. If your sketch does not display anything, run an I2C scanner sketch to confirm the address.

Can I show images and custom fonts?

Yes. With Adafruit GFX or U8g2 you can draw text in multiple fonts, shapes, and monochrome bitmaps up to the full 128x64 resolution.

What comes in the box?

You receive the OLED display module itself with the 4-pin header pre-soldered (or as a strip on some batches). Jumper wires and boards are not included.
