LCD2004 Backlight Development Board IIC I2C Interface Yellow Green Backlight Module 3-6V 20*4 Character for Arduino DIY

LCD2004 Serial Interface Adapter Module IIC I2C Interface Backlight Development Board 3-6V 20*4 Character Electronic Components
Features:
1.Efficient I2C Interface: The 2004A LCD screen module can be easily controlled using the I2C interface, requiring only two pins for communication. By utilizing the I2C protocol, this module significantly reduces the number of IO resources needed on your microcontroller or development board, allowing you to optimize your project’s design and connectivity.
2.LCD Brightness Control: The serial interface adapter module features a convenient potentiometer that enables easy adjustment of the LCD brightness. You can fine-tune the brightness level according to ambient lighting conditions or personal preference. This user-friendly feature ensures optimal visibility and readability in various environments.
3.Optional Backlight Configuration: The backlight development board provides flexibility in backlight usage. By simply adjusting a jumper, you can decide whether the LCD module should come with a backlight or not. This allows you to adapt the module to specific requirements, such as power-saving purposes or applications where backlighting is unnecessary.
4.Adjustable Contrast: Achieve the desired contrast for your LCD display with the help of the onboard potentiometer. This adjustable feature allows you to optimize the contrast level, resulting in improved visibility and legibility of displayed content. Whether you need to enhance readability in bright environments or improve aesthetics, this module offers versatility and customization options.
5.Modify I2C Address: The LCD screen module’s I2C address can be modified to avoid conflicts when integrating multiple I2C devices into your project. This flexibility allows for seamless compatibility and smooth operation when connecting the module with other I2C-enabled devices. The module comes with default addresses set at 0x3F or 0x70, ensuring ease of use without additional configuration.
