KEYESTUDIO 20x4 LCD Display IIC/I2C/TWI 2004 Display for Arduino Uno r3 Mega 2560 Raspberry Pi Avr Stm32

Introduction keyestudio 2004 I2C Module is a 20 character by 4 line LCD display with Blue background and White backlight. The original 2004 LCD needs 7 IO ports to be up and running, ours is built with Arduino IIC/I2C interface, saving you 5 IO ports. This LCD is ready-to-use because it is compatible with the Arduino Liquid Crystal Library. This module carries I2C interface, so we need to comply with I2C protocol in usage and corresponding head files must be included and added into the library. Specification Interface: I2C I2C address: 0x27 Operating voltage: +5V Size: 27.7mm¡Á42.6mm Contrast control: via potentiometer Package List: 1 x 2004 I2C Module
