16x2 LCD display - Blue backlight

Display Size: A 16x2 LCD display typically consists of 16 characters per line and 2 lines, allowing it to display a total of 32 characters. Each character is made up of a 5x8 pixel matrix.

LCD Technology: These displays use liquid crystal technology to control the passage of light, enabling the display of text and simple graphics.

Blue Backlight: The blue backlight provides illumination to the characters, making them visible in low-light conditions or in the dark. The backlight can usually be controlled separately from the text display.

Contrast Adjustment: Many LCD displays allow for the adjustment of the contrast to optimize the readability of the characters on the screen.

Parallel Interface: These displays typically use a parallel interface for communication with microcontrollers and other devices. They require multiple GPIO pins for data and control signals.

Voltage Requirements: The operating voltage for 16x2 LCD displays is often in the range of 4.5V to 5.5V, but it may vary by manufacturer.

Character Set: These displays support displaying alphanumeric characters (letters and numbers), symbols, and custom characters if supported by the controller.

Applications: 16x2 LCD displays are widely used in various applications, including embedded systems, digital clocks, temperature and humidity displays, data loggers, home automation, and educational projects.

Library Support: Many microcontroller platforms have libraries or code examples available to simplify interfacing with 16x2 LCD displays.

Mounting: These displays often include mounting holes for secure attachment to a project or enclosure.
