Description
Product Overview
The 0.96-inch 7-Pin Blue OLED Display Module is a compact, high-contrast graphic display featuring the SSD1306 driver IC and a crisp 128×64 pixel resolution . This 7-pin variant offers the greatest flexibility, supporting both SPI and IIC communication protocols, with SPI selected by default . The dedicated CS (Chip Select) pin allows you to use multiple devices on the same SPI bus without conflicts.
OLED (Organic Light-Emitting Diode) technology requires no backlight, as each pixel emits its own light. This results in true blacks (inactive pixels are completely off), an exceptional >160° viewing angle, and significantly lower power consumption than traditional LCDs .
This module is ideal for Arduino, ESP32, ESP8266, STM32, and Raspberry Pi projects. Common applications include sensor monitors, IoT dashboards, menu interfaces for handheld devices, data loggers, and diagnostic tools .
Key Features
-
128×64 Pixel Resolution: High-definition display delivers crisp text, custom graphics, and detailed bitmaps
-
2-in-1 Communication Flexibility: Supports both SPI (default) and IIC protocols—switchable by moving a surface-mount resistor on the back
-
Blue Monochrome OLED: Vibrant blue pixels on true black background for exceptional readability
-
Dedicated CS Pin: Independent Chip Select line enables multiple SPI devices on the same bus without conflicts
-
SSD1306 Driver IC: Industry-standard controller with built-in display buffer and extensive library support
-
Wide Voltage Compatibility: Operates on 3V-5V DC, compatible with both 3.3V (ESP32) and 5V (Arduino) logic
-
Ultra-Low Power Consumption: Uses approximately 0.08W (full screen lit) since no backlight is needed
-
Wide Viewing Angle: >160° visibility ensures clear readouts from almost any angle
-
Wide Operating Temperature: Industrial-grade rating of -40°C to +85°C
