    3pc PCF8574 I2C LCD Adapter Module is a compact serial interface board designed to simplify control of LCD1602 (16×2) and LCD2004 (20×4) character displays. By using the PCF8574 I/O expander chip, it converts a parallel LCD connection into a 2-wire I2C (SDA/SCL) interface, drastically reducing wiring complexity and saving valuable GPIO pins on your microcontroller.

    Operating at 5V (compatible with 2.5V6V), this module features an adjustable contrast potentiometer and a backlight jumper for easy display optimization. The default I2C address is 0x27, which can be modified via A0/A1/A2 solder pads, allowing multiple modules to be cascaded on a single I2C bus.

    Perfect for Arduino, ESP32, ESP8266, Raspberry Pi, and robotics projects, this adapter turns any standard LCD into an easy-to-use I2C display for data logging, sensor readouts, and embedded system interfaces.
