SH1106 1.3 inch I2C OLED Display Module

A 1.3-inch I2C OLED display module with 128x64 resolution is a compact, high-contrast display ideal for Arduino projects. It typically uses the SH1106 controller (sometimes SSD1306, so verify your module) and communicates via I2C, requiring only four pins: VCC (3.3V or 5V), GND, SCL (serial clock), and SDA (serial data).

Features:

• Resolution: 128x64 pixels
• Size: ~3.7 cm diagonal
• Controller: Usually SH1106 (check your module; some use SSD1306)
• Interface: I2C (simpler wiring than SPI)
• Power: 3.3V–5V, low power (~0.04W)
• Viewing Angle: >160°
• No backlight: Self-illuminating pixels for high contrast and deep blacks
