20x4 Character LCD Module with Blue Backlight, 3.3V

This 20x4 character LCD module provides a clear text display with a high-contrast blue backlight, operating at a low 3.3V logic level. It is ideal for makers, students, and hobbyists looking to add visual feedback and status monitoring to their electronics and microcontroller projects.

Clear character display

The module displays 20 characters across 4 lines, providing ample space to output project data, sensor readings, and system messages against an illuminated blue background.

3.3V low-voltage operation

Designed to run at 3.3V, this display is suited for low-power and 3.3V logic microcontrollers and developmental setups without requiring external logic level shifting.

Standard parallel interface

This unit uses a traditional direct parallel connection rather than an integrated I2C backpack interface, giving you direct pin-level control over the display lines.
