1-10PCS PCF8574 LCD Display Adapter Module IIC I2C LCD1602 2004 IIC Serial Interface Board 5V for Arduino Robort Parts PCF8574 LCD Adapter Converter Module IIC I2C LCD1602 2004 IIC Serial Interface Adapter 5V for Arduino Robort Parts Features: 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. 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 : 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. 1*LCD Adapter Converter Module
