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. ✨ Features ✔ 16×2 character LCD module✔ Comes with I2C backpack (PCF8574)✔ Works on 5V supply✔ Adjustable contrast using onboard potentiometer✔ Supports Arduino LiquidCrystal_I2C library✔ Requires only 2 communication pins✔ Available in Green or Blue backlight✔ Long life and low power consumption✔ Compatible with Arduino, ESP32, ESP8266, and other MCUs ��️ Technical Specifications Display Type: 16×2 LCD (1602A) Interface: I2C (PCF8574) Operating Voltage: 5V Number of Characters: 16 × 2 Backlight Colors: Green / Blue Contrast Adjustment: Yes (Potentiometer) I2C Address: 0x27 (default) Controller: HD44780 compatible �� Package Includes 1 × 16×2 LCD Display 1 × I2C Module (pre-soldered) �� Applications IoT devices Sensor data display Home automation Robotics Industrial monitoring Weather stations Educational projects
