The LCD2004 (20x4) is designed with an industry standard HD44780 equivalent LCD controller.
The module provides a simple and cost-effective solution for adding a 20x4 character display to your project. It offers a very clear and high contrast text upon the background/backlight.
It operates with a 5V DC and comes with a single LED backlight that can easily be dimmed using a resistor or PWM.
The LCD can operate in 2 different modes:
- In 8 bit mode, all 8 data pins of the LCD are used.
- In 4 bit mode, only the 4 data pins of the LCD are used.
Therefore it can be controlled with only 6 digital lines (4-DATA + RS + EN).
To reduce the pin connection with the MCU, you can use PCF8574 LCD Controller
