I2C Module for LCD 16x2 display
The I2C Module is used to reduce the no. of pins needed for the display. It enables the display to work with only four pins. The LCD Display can be used with all Microcontroller boards like 8051, AVR, Arduino, PIC, and ARM Microcontrollers. The I2C LCD Interface Module enables easy and efficient communication between microcontrollers and standard 16x2 or 20x4 LCD displays using just 2 signal wires (SDA, SCL). It s ideal for Arduino, ESP32, STM32, and Raspberry Pi based systems where GPIO pins are limited.
