LCD 1602 with I2C is a 16x2 character Liquid Crystal Display (LCD) module with an I2C (Inter-Integrated Circuit) interface. This module is commonly used in microcontroller projects (e.g., Arduino, Raspberry Pi) to display text and simple data.
16x2 Display – Can show 16 characters per line and has 2 rows.
I2C Interface – Uses only two data pins (SDA & SCL), reducing the number of required connections.
Backlight and Contrast Control – Includes an adjustable potentiometer for contrast and an LED backlight.
PCF8574 I2C Expander – Converts the standard parallel interface of the LCD to I2C, simplifying wiring.
Compatible with Arduino, ESP8266, ESP32, Raspberry Pi, and other microcontrollers.
