1.3 Inch OLED Display Module 16-KEY Yellow Keyboard SH1116 128×64 I2C Interface

1.3 Inch OLED Display Module 16-KEY Yellow Keyboard SH1116 128×64 I2C Interface is a highly integrated human-machine interface (HMI) component designed to combine visual output and user input into a single compact board. This innovative module features a high-contrast 1.3-inch OLED screen driven by the advanced SH1116 controller, delivering crisp 128×64 resolution graphics without requiring a backlight. Consequently, it provides exceptional readability from extreme viewing angles while maintaining ultra-low power consumption. Furthermore, the built-in 16-key matrix keypad featuring distinct yellow keycaps allows users to enter numeric data and navigate menus effortlessly. Therefore, developers can significantly simplify their circuit design and save valuable micro-controller I/O pins by using this unified display and keypad module over a streamlined I2C bus interface.

Key Features:

• High-Contrast OLED Screen: Emits self-illuminating light to ensure vibrant visuals, deep blacks, and sharp text readability under various lighting conditions.
• Integrated 16-Key Keypad: Incorporates a full 4×4 matrix keyboard with eye-catching yellow keys, enabling immediate user input for menu selection and password entry.
• Efficient I2C Interface: Communicates over a simple 2-wire serial bus, which drastically reduces the required GPIO connections on host microcontrollers.
• Low Power Consumption: Consumes minimal electrical power because OLED technology lights only the active pixels, extending battery life in portable setups.
• Wide Viewing Angle: Offers an expansive viewing angle exceeding 160°, ensuring clear visual feedback from virtually any position.
