Blue LCD 1602 16x2 HD44780 display with I2C converter, Arduino screen

Product description

LCD 1602 16x2 display with a factory-soldered I2C HD44780 converter is an excellent choice for displaying information in electronic projects. The module works well in building controllers, meters, and alarm systems. Thanks to blue backlighting and white characters, the screen provides excellent readability even in low light. It displays 2 lines of text with 16 characters each.

The I2C interface greatly simplifies mounting and integration with popular microcontrollers. The module is ideal for Arduino, for ESP8266, for ESP32, and for Raspberry Pi. The built-in potentiometer allows smooth adjustment of contrast and backlight control, so you can adapt it to the lighting conditions.
