CHARACTER

Character LCD displays are widely used for displaying alphanumeric information in embedded systems, microcontroller projects, and industrial control panels. These modules show fixed numbers of characters per line, such as 16×2, 20×4, or 40×2, and are a reliable choice for status monitoring, menu navigation, or debugging.

Key features of character LCDs:

• Common formats: 16x2, 20x4, 40x2

• Backlit and non-backlit versions

• Standard HD44780-compatible controllers

• Interfaces: Parallel (4-bit/8-bit) and I2C adapters available

• Languages & characters: ASCII, Japanese, Cyrillic (model dependent)

Character LCDs are compatible with most microcontrollers like Arduino, ESP32, AVR, PIC, and STM32, with well-documented libraries (e.g., LiquidCrystal, LiquidCrystal_I2C).

These displays are ideal for:

• DIY electronics projects

• Temperature/humidity displays

• Voltage/current meters

• Simple human-machine interfaces (HMI)

• Appliance interfaces
