JOY-IT SBC-LCD16x2 I2C LCD Display Module for Raspberry Pi, 16x2 Characters, Green/Blue Backlight

Raspberry Pi projects often need a simple way to display status, sensor readings, or system information without a bulky monitor. The JOY-IT SBC-LCD16x2 solves this by providing a compact 16x2 character LCD with an I2C interface, using only four wires to connect to your Raspberry Pi. The display features a selectable green or blue backlight, making it easy to read in various lighting conditions. With its HD44780-compatible controller and pre-soldered I2C adapter, you can integrate it into your projects quickly and with minimal GPIO usage.

Who is it for

This module is ideal for hobbyists, makers, and professionals working with Raspberry Pi A+, B, 2 B, 3 B, 4 B, or Zero. Whether you're building a home automation dashboard, a weather station, a system monitor, or any project that needs a simple text display, this LCD provides a reliable and easy-to-use solution. No soldering is required, and the I2C interface keeps your GPIO pins free for other components.

Tips

To get started, connect the module to your Raspberry Pi's 5V, GND, SDA (GPIO 2), and SCL (GPIO 3) pins. Enable I2C in raspi-config and install the necessary libraries. The I2C address is typically 0x27, but you can verify with i2cdetect. Adjust the contrast potentiometer if the characters are not visible. For custom characters, refer to the HD44780 datasheet to define your own symbols.
