Description
Product Overview
The 1.3-inch I2C OLED Display Module is a compact, high-contrast monochrome screen designed for embedded projects requiring crisp visual output without consuming excessive power or I/O pins. Powered by the SH1106 driver IC and featuring a sharp 128×64 pixel resolution, this display delivers vibrant text, detailed graphics, and custom icons in either striking blue or clean white .
Unlike traditional LCDs that require a power-hungry backlight, OLED (Organic Light Emitting Diode) technology allows each pixel to emit its own light. This self-emissive design provides true blacks (inactive pixels are completely off), an exceptional 10,000:1 contrast ratio, and >160° viewing angles – ensuring the display remains readable from almost any angle .
The module uses the 4-pin I2C interface (VCC, GND, SCL, SDA), requiring only two data lines to connect to your microcontroller. This preserves valuable I/O pins for other sensors and peripherals . With support for both 3.3V and 5V logic, it is directly compatible with Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and most other development boards – no level shifters required .
Key Features
-
1.3-Inch Active Area: Larger than 0.96″ OLEDs, offering 34.5mm × 19mm display area for better readability
-
128×64 Pixel Resolution: High-definition display with 128 columns and 64 rows – capable of showing detailed graphics, bitmaps, and up to 8 lines of small text
-
SH1106 Driver IC: Industry-standard controller with built-in 132×64-bit SRAM buffer (supports 128×64 active area)
-
I2C Interface: 2-wire communication requires only 2 data lines (SCL and SDA) – saves valuable I/O pins
-
Wide Voltage Compatibility: Operates on 3.3V–5V DC, compatible with both 5V (Arduino) and 3.3V (ESP32/ESP8266) logic
-
Ultra-Low Power Consumption: Uses approximately 0.04W (typical operation) – no backlight means lower battery drain
