Gravity: I2C 16x2 Arduino LCD with RGB Backlight Display

A 16×2 character LCD module with full RGB backlight, communicating over I2C for minimal wiring. With support for 16 million backlight colours, this display adds a vibrant, customisable readout to your Arduino or compatible microcontroller projects using just four wires: VCC, GND, SDA, and SCL.

Part of the DFRobot Gravity ecosystem, the module features a standard Gravity 4-pin I2C connector for plug-and-play use with Gravity-compatible shields and boards. It also works with any I2C-capable microcontroller at 3.3 V or 5 V logic levels.
