Overview

This DFRobot 16×2 character LCD module gives Arduino projects a simple text display with an I2C interface. It uses only four connections—VCC, GND, SDA, and SCL—so it can help reduce wiring and free up I/O pins.

The display shows 16 white characters across 2 lines on a blue backlight. It also includes adjustable contrast and a configurable I2C address, which can be useful when multiple I2C devices share the same project.

It is listed as compatible with common Arduino boards such as UNO, Leonardo, Mega, Micro, Nano, and Mini. Typical uses include sensor readouts, counters, timers, status panels, and classroom or prototyping projects.
