Original price was: ₹60.00.₹42.00Current price is: ₹42.00.
(-30%)I2C serial backpack module based on the PCF8574 I/O expander that enables 16×2 and 20×4 character LCDs to be controlled using only two microcontroller pins (SDA and SCL).
Product details
The I2C LCD Interface Module is designed to simplify the connection of HD44780-compatible LCD displays by converting the parallel interface into an I2C interface. Built around the PCF8574 I/O expander IC, the module reduces the number of required microcontroller pins from 6–8 to just 2. It features an onboard contrast adjustment potentiometer and supports popular development platforms including Arduino, ESP32, ESP8266, STM32, and Raspberry Pi. This module is commonly used in embedded systems, IoT projects, industrial displays, and educational electronics projects.
