## Description

A 20×4 character I2C LCD display module compatible with Arduino and other microcontrollers. It shows white characters on a blue backlit background, and the I2C interface means you only need two data pins (SDA and SCL) instead of the six or more required by a standard parallel LCD. The module supports both 5 V and 3.3 V power, making it compatible with Arduino UNO, Arduino Mega, Arduino Due, and other 3.3 V systems. Contrast is adjustable manually, and eight selectable I2C addresses (0x20–0x27) let you avoid bus conflicts when using multiple I2C devices. Key Features 20×4 Character Display – 80 characters across four lines I2C Interface – Only two data pins required (SDA, SCL) Dual Voltage Support – 5 V via pin header or 3.3 V via IDC10 connector Selectable I2C Address – Eight addresses from 0x20 to 0x27 (0x20 default) Adjustable Contrast – Manual contrast adjustment Blue Backlight – White characters on blue background Specifications Display – 20 characters × 4 lines Dot Size – 0.55 × 0.55 mm Character Size – 2.96 × 4.75 mm Character Pitch – 3.55 × 5.35 mm Interface – I2C/TWI ×1, IDC10 ×2 I2C Connector – VCC, GND, SCL, SDA Dimensions – 98 × 60 × 24 mm Package Contents 1× I2C 20×4 Arduino LCD display module Resources Wiki page Schematic (PDF) Arduino sample code LCD datasheet (PDF) PCA8574 datasheet (PDF)
