16x2 Blue LCD Display for Arduino

16x2 Blue LCD Display for Arduino – HD44780 Compatible

The 16x2 Blue LCD Display is a versatile alphanumeric module featuring 16 characters by 2 lines, designed for Arduino, Raspberry Pi, and other microcontroller projects. With crisp white characters on a vivid blue backlight, this 1602 character LCD display is ideal for electronics prototyping, embedded systems, and DIY automation. Whether you're building a temperature monitor, a user interface, or a robotics project, this module delivers clear visual output with minimal resource use.

This display is based on the HD44780 or SPLC780D1 controller, supporting both 4-bit and 8-bit parallel interfaces. It only requires 6 digital I/O pins for basic operation, making it compatible with nearly all microcontrollers, including Arduino Uno, Mega, Nano, ESP32, and more. The LED backlight ensures visibility in low-light environments, while the COB (Chip-on-Board) design ensures long-term durability.

With a 5x7 dot matrix per character and adjustable contrast, this 16x2 blue LCD screen offers sharp readability from a 6 o'clock viewing angle. It operates at 5V, has a wide temperature tolerance, and is ideal for classroom use, hobby projects, or professional electronics development.
