The 1602 LCD display module with I2C interface is a popular choice for Arduino and other microcontroller projects due to its simplicity and ease of use. Here are the specifications:

1602 LCD Display Module Specifications:

• Display Type: Character LCD
• Characters: 16 characters x 2 lines
• Character Size: 5×8 dot matrix
• Interface: Parallel (standard) or I2C (with module)
• Backlight: Blue with white text
• Operating Voltage: 4.7V to 5.3V
• Viewing Angle: Wide

I2C Interface Module Specifications:

• I2C Address: Usually 0x27 or 0x3F (can vary, check your module documentation)
• Voltage: 5V (powered from the LCD module)
• Interface: I2C (SDA and SCL pins)
• Adjustable Contrast: Potentiometer on the I2C module
• Libraries Required: Often requires a library like LiquidCrystal_I2C for Arduino

Pin Configuration for I2C Module:

• VCC: Connect to 5V
• GND: Connect to Ground
• SDA: Serial Data Line (connect to SDA on microcontroller, e.g., A4 on Arduino Uno)
• SCL: Serial Clock Line (connect to SCL on microcontroller, e.g., A5 on Arduino Uno)

Additional Features:

• Backlight Control: Some I2C modules allow you to control the backlight via software
• Adjustable Contrast: Using the potentiometer on the I2C module

Typical Dimensions:

• Module Size: Approximately 80mm x 35mm x 12mm (length x width x height)
• Viewing Area: Approximately 64.5mm x 16mm

Usage Notes:

• Ensure the correct I2C address in your code.
• Use appropriate libraries to simplify interfacing.
• Contrast may need adjustment using the potentiometer for optimal display readability.
• When wiring, ensure connections are secure to avoid display issues.
