Description:
The I2C LCD Module Adapter is a tiny interface board that allows conventional HD44780-based LCDs (such as 16x2 or 20x4 screens) to interact over the I2C protocol, considerably decreasing the number of required microcontroller pins.
Instead of using 6-10 digital pins for parallel communication, this adaptor allows control via only two wires: SDA and SCL.
It includes the PCF8574 I/O expander chip, which converts I2C signals into parallel signals that work with the LCD.
The adapter has an inbuilt potentiometer for contrast adjustment, a jumper for backlight control, and solder pads for easy installation.
This module is perfect for the Arduino, Raspberry Pi, ESP8266/ESP32, and other microcontroller platforms that require pin conservation and reduced cabling.
