LCD 1602 16×2 Character Display with I2C Interface – Blue Backlight
Product Description
This 16×2 LCD module combines a clear blue-backlit character display with an integrated I2C interface. It can show up to 16 characters on each of its two rows and is ideal for displaying sensor readings, status messages, counters, menus and other project information.
The I2C interface significantly reduces wiring and typically requires only four connections: VCC, GND, SDA and SCL. This saves valuable microcontroller pins compared with a standard parallel LCD connection.
The module is compatible with Arduino, Raspberry Pi, ESP8266, ESP32 and many other supported development boards. Its onboard potentiometer allows the display contrast to be adjusted easily.
