The mLink Character LCDs are serial (I2C/IIC) LCD displays available in either 16 column by 2 row (16x2), or 20 column by 4 row (20x4) options. Because they use a standard I2C interface they are compatible with most microcontrollers including Arduino, are addressable (address can be changed in software), and only require 2 data pins for communication. Unlike standard serial or parallel character displays they require no configuration or setup to use them saving on development time and code size.

Elizabeth ★★★★★

I connected this 20x4 I2C display to my Arduino in under five minutes and the text is crisp even at small font sizes. The backlight is bright enough to read from across the desk.

Sebastian O. ★★★★★

The 20x4 display is the perfect size for showing sensor data without scrolling. Setting it up on I2C was incredibly simple with just two wires needed.

Daniel ★★★★★

I plugged this into my Arduino project and the I2C interface meant only two wires were needed—much cleaner than the parallel LCDs I've used before. The 20x4 display gives me plenty of room for sensor readings and menus without any flicker. Perfect for cramped enclosures.
