RGB 16×2 LCD Display (I2C, 3.3V/5V)

LCD displays are a fun way to learn how to code with a Raspberry Pi, Arduino and most development boards, however they usually come with a lot of pin connections and a single backlight colour.

This Waveshare LCD1602 version of the classic 16×2 LCD Display has an RGB backlight, allowing you to select up to 16 million different colours for your project. It also features an I2C interface requiring just 4 pin connections, making wiring your project much easier and reducing cable spaghetti!

Add the smooth rounded edges, handy mounting holes and included jumper wire and you’ve just found the ultimate LCD upgrade!

Examples are provided for the Raspberry Pi, Raspberry Pi Pico and Arduino.
