Overview
This 16×2 LCD Display with I2C is one of the most popular display modules used in electronics, embedded systems, and IoT projects. It can display 16 characters per line and 2 lines, making it perfect for showing sensor values, menu systems, device status, and debug information.
The added I2C backpack module significantly reduces wiring—from 16 pins to just 4 pins (VCC, GND, SDA, SCL). This makes it ideal for Arduino, ESP32, ESP8266, and Raspberry Pi users who want clean and simple connections.
