Gravity: I2C 16x2 RGB LCD
Overview
The DFR0464 is a 16x2 character LCD module featuring an integrated RGB backlight and an I2C interface for simplified wiring. Part of the DFRobot Gravity ecosystem, it allows for custom background colors and character display using only two data pins.
Why Choose This Part
The I2C interface significantly reduces wiring complexity compared to standard parallel LCDs, requiring only four connections (VCC, GND, SDA, SCL). The RGB backlight adds a layer of status signaling, allowing engineers to use color as a non-textual data indicator.
Applications
Key Specifications
Getting Started
Connect the module to any microcontroller with an I2C bus using the included Gravity cable. Use the DFRobot_RGBLCD memory-efficient library for Arduino to control text alignment and backlight color via standard hexadecimal or RGB values.
