Specification: Origin: Mainland China Type: Module Condition: New 1. Power Supply Voltage: 3-6V 2. Support I2C Protocol 3. Setting Whether With Backlight Or Not By Jumping Up And Down 4. Contrast Can Be Adjusted Through The Potentiometer 5. Product Size: 42.00x40.00x15.00mm/1.65x1.57x0.59inch Product Description: 1. LCD1602/2004 connected to the microcontroller will occupy many 1O port. This module can be directly driven by 2C interface. 2. LCD1602/2004, and 2C only need two ports, greatly saving the microcontroller 1O port resources. Module also has 3. A potentiometer to adjust the brightness of the LCD, very convenient to use. Note: Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you! Please allow 1-2cm measuring deviation due to manual measurement. Included: 1*LCD Adapter Converter Module 1.Simplified Connection: This LCD adapter converter module utilizes the IIC/I2C interface, simplifying complex pin connections to just two wires (SDA and SCL), reducing the risk of connection errors and wiring difficulties. 2.IO Resource Saving: Traditional LCD screens require multiple GPIO pins for control, but with the IIC/I2C interface of this LCD adapter plate, communication can be achieved using only two GPIO pins, saving valuable IO resources on your microcontroller. 3.Expandability: Through the IIC/I2C interface, this IIC serial interface adapter easily connects to multiple devices (such as other sensors or modules), greatly enhancing the system's expansion capabilities and allowing for seamless integration with a wide range of components. 4.Fast Data Transfer: The IIC/I2C interface offers high-speed data transfer, allowing the LCD display adapter module to quickly transmit data to the LCD screen for display. This results in lower latency and smoother visual effects. 5.Wide Compatibility: The IIC/I2C interface is a widely supported serial communication protocol, making this IIC serial interface board compatible with many main controllers and development platforms, ensuring versatility and ease of integration.
