Character LCD 16×2 Display Module

The Character LCD 16×2 Display Module is a popular display unit capable of showing 16 characters per line across 2 lines, making it ideal for simple user interfaces in electronic projects. Based on a standard controller (commonly HD44780 or compatible), it provides an easy way to display text, numbers, and basic symbols. Its parallel interface allows direct connection to microcontrollers such as Arduino, Raspberry Pi (via interface), and other development boards.

This module is highly favoured for its simplicity, low cost, and ease of integration. It supports both 4-bit and 8-bit communication modes, reducing the number of required I/O pins when needed. With adjustable contrast and optional backlight, the display ensures clear readability in various lighting conditions. It is widely used in educational, industrial, and hobbyist applications where simple visual feedback is required.

Features:

• 16 characters × 2 lines.
• Built-in ST7066 controller (HD44780 compatible).
• 5×8 dot matrix with cursor.
• Transflective FSTN positive display.
• 6 o’clock viewing direction.
• RGB triple-color LED backlight (individually controlled).
• 8-bit or 4-bit parallel interface.
• Wide operating temperature range.
• Low power logic operation.
• Supports custom characters (CGRAM).
• RoHS compliant.
