I2C Graphic 128 x 64 LCD Display Adapter

Power

The I2C Graphic 128 x 64 LCD Display operates within a voltage range of 3.3V to 5V. The current consumption is minimal, usually around 10-20mA, making it energy efficient for most applications. It can be powered directly from the microcontroller or an external power supply.

Input and Output

The display module uses the I2C protocol for data communication. It receives input data via the SDA (Serial Data) and SCL (Serial Clock) lines, which are standard for I2C communication. The output is a visual representation on the screen, displaying text, graphics, or custom symbols.

Physical Characteristics

This LCD module is compact, measuring around 45mm x 35mm x 5mm. The display area is 128 x 64 pixels, which is sufficient for displaying text, small graphics, or a combination of both. The module usually comes with mounting holes for easy installation onto various surfaces or enclosures. The lightweight and small form factor make it ideal for portable or space-constrained projects.
