1.3 Inch OLED Display Module 4-KEY Yellow Keyboard SH1116 128×64 I2C Interface

1.3 Inch OLED Display Module 4-KEY Yellow Keyboard SH1116 128×64 I2C Interface is a highly integrated display and control solution designed for interactive embedded systems and smart hardware prototypes. This module combines a crisp 1.3-inch OLED screen driven by the efficient SH1116 controller with an integrated 4-key yellow tactile keyboard. Consequently, developers can implement both visual feedback and user navigation without needing separate control boards. The 128×64 pixel resolution delivers sharp, self-illuminating graphics with high contrast, making the text easily readable even in low-light environments. Furthermore, the simplified I2C interface requires minimal GPIO pins from your microcontroller. Therefore, you can easily connect this module to Arduino, ESP32, or Raspberry Pi boards to build portable devices, custom menu systems, and compact instruments.

Key Features:

• Integrated 4-Key Keypad: Features four yellow tactile push buttons on board, enabling direct menu control and navigation without external switches.
• High-Contrast OLED Screen: Emits light independently without requiring a backlight, providing exceptionally high contrast, deep blacks, and wide viewing angles.
• Efficient SH1116 Driver: Uses the reliable SH1116 display driver IC to render 128×64 pixels smoothly over a standard 2-wire serial bus.
• Simplified I2C Interface: Communicates via I2C protocol, which conserves valuable GPIO pins on your host microcontroller.
• Low Power Consumption: Consumes very little power during operation, making it an ideal choice for battery-powered handheld equipment.
