LCD 20×4 Alphanumeric Display with soldered I²C/IIC interface – Green Backlight

The LCD 20×4 Alphanumeric Display with soldered I²C/IIC interface (Green Backlight) is a versatile module designed for microcontroller and embedded system projects. Featuring 20 characters × 4 lines, it provides clear text output for menus, sensor readings, and status messages.
The integrated I²C/IIC interface reduces wiring complexity to just two data lines (SDA, SCL) plus power, making it ideal for Arduino, Raspberry Pi, ESP32, STM32, and other controllers. The green LED backlight ensures excellent visibility in all lighting conditions.
