Upgrade your LCD projects with the ElectroGlobal I2C Serial Interface LCD Adapter Module. Designed to simplify connections, this module reduces the number of GPIO pins required, making it easy to interface a 1602 or 2004 LCD display with microcontrollers like Arduino, ESP8266, Raspberry Pi, and more. The built-in PCF8574T I2C chip allows smooth two-wire communication via SDA and SCL pins, while the onboard potentiometer enables contrast adjustment for better display readability.
