20Pcs PCF8574 I2C IIC LCD1602 2004 Display Adapter Module LCD Interface Converter Board for Robot Parts leírása

The PCF8574 LCD adapter module is designed to simplify the connection between standard character LCD displays (such as 1602 and 2004 modules) and microcontrollers

By converting the LCD interface to I2C/IIC, it significantly reduces the number of I/O pins required, making it ideal for projects, robot parts integration, and other DIY electronics applications
Compatible with 1602/2004 LCDs: Supports common LCD1602 and LCD2004 character displays, allowing flexible use in a wide range of display projects
I2C/IIC Interface: Utilizes the PCF8574 I/O expander chip to convert the parallel LCD interface into a simple two‑wire I2C bus, saving valuable MCU pins
Compact PCB Design: Small, module that mounts directly onto the back of the LCD display, saving space in your enclosure
