1.3 Inch I2C/IIC $128 \times 64$ Monochrome OLED Display Module (4-Pin, White Pixels, SH1106 Driver)

Add crisp, self-luminous graphical interfaces to your embedded electronics with the 1.3 Inch I2C $128 imes 64$ White OLED Display Module. Powered by the high-performance SH1106 controller IC, this compact display panel renders sharp white text, micro-graphs, and custom icons across $128 imes 64$ individual pixels without requiring a backlight. Communicating over a simple 4-pin I2C bus (VCC, GND, SCL, SDA), it operates on $3.3 ext{V}$ to $5.0 ext{V DC}$ logic and boasts an ultra-wide viewing angle ( $>160^circ$ ) with extremely low power consumption. It is fully compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and STM32 using standard display libraries like U8g2 and Adafruit_SH110X.

Product Details :

The 1.3 Inch I2C $128 imes 64$ White OLED Display Module is a low-power, high-contrast visual display module engineered for space-constrained embedded systems. Built on Organic Light-Emitting Diode (OLED) display technology, every pixel emits its own light, eliminating the need for a power-hungry backlight unit. This allows deep, true black levels and exceptionally high contrast ratios that keep text and graphics clear even in brightly lit environments.

Driven by the popular SH1106 controller IC (SSD1306-compatible software command set), this module uses a minimalist 4-wire I2C interface consisting of power ( $VCC, GND$ ) and two signal lines ( $SCL, SDA$ ). Onboard voltage regulators and level shifters support dual operating voltage levels from $3.3 ext{V}$ to $5.0 ext{V DC}$ , allowing seamless direct connection to both $3.3 ext{V}$ microcontrollers (ESP32, ESP8266, Raspberry Pi Pico) and $5 ext{V}$ boards (Arduino Uno, Mega, Nano) without external logic shifters.

Key Features and Benefits

High-Contrast Self-Luminous Pixels: Emits vivid white light per pixel ( $128 imes 64$ matrix) with deep blacks and zero backlight bleed.
Ultra-Wide Viewing Angle: Provides consistent readability from angles exceeding $160^circ$ .
Simplified 4-Pin I2C Bus: Requires only 2 microcontroller GPIO pins ( $SDA$ and $SCL$ ) to drive the display, saving precious system pins.
Broad Voltage Compatibility ( $3.3 ext{V} - 5.0 ext{V}$ ): Integrated voltage level conversion supports both $3.3 ext{V}$ and $5 ext{V}$ system logic natively.
Ultra-Low Power Consumption: Consumes only $sim8 ext{mA}$ under average full-screen usage, making it ideal for battery-operated wearables and IoT devices.
Extensive Open-Source Software Support: Easily programmed using community libraries such as U8g2, U8glib, or Adafruit_SH110X.

2. Microcontroller Wiring Table:

OLED Pin	Arduino Uno / Nano	ESP8266 (NodeMCU)	ESP32	Raspberry Pi Pico
$GND$	$GND$	$GND$	$GND$	$GND$
$VCC$	$5 ext{V}$ / $3.3 ext{V}$	$3.3 ext{V}$	$3.3 ext{V}$	$3.3 ext{V (OUT)}$
$SCL$	Pin $A5$	$D1$ ( $GPIO5$ )	$GPIO22$	$GP1$ ( $I2C0 SCL$ )
$SDA$	Pin $A4$	$D2$ ( $GPIO4$ )	$GPIO21$	$GP0$ ( $I2C0 SDA$ )

SOFTWARE CONGRUENCE NOTE: Although physical resolution is $128 imes 64$ , the SH1106 driver internal RAM is structured as $132 imes 64$ . When configuring libraries like U8g2, make sure to select the SH1106 $128 imes64$ driver constructor (rather than SSD1306) to ensure the image centers correctly on the display glass without horizontal offsets.
