The IIC/I2C Interface LCD1602 Adapter Board is a compact module designed to simplify connections between a microcontroller and a compatible 1602 character LCD display. It uses the I2C communication interface to reduce the number of required wiring connections compared with a traditional parallel LCD interface.
The adapter is commonly based on a PCF8574 I/O expander and is suitable for Arduino, microcontroller, and DIY electronics projects. It typically provides a contrast adjustment potentiometer and an onboard backlight control jumper.
